Trust His Heart

All things work for our good
Though sometimes we can’t see how they could
Struggles that break our heart in two
Sometimes blind us to the truth

Our Father knows what best for us
His ways are not our own
So when your pathway grows dim
And you just can’t see Him
Remember you’re never alone

God is too wise to be mistaken
God is too good to be unkind
So when you don’t understand
When you don’t see His plan
When you can’t trace His hand
Trust His Heart

He sees the master plan
He holds the future in His hand
So don’t live as those who have no hope
For our hope is found in Him

We see the present clearly
But He sees the first and the last
And like a tapestry He’s weaving you and me
To someday be just like Him

God is too wise to be mistaken
God is too good to be unkind
So when you don’t understand
When you don’t see His plan
When you can’t trace His hand
Trust His Heart

He alone is faithful and true
He alone knows what is best for you

He whose heart is kind beyond all measure
Gives unto each day what He deems best
Lovingly its part of pain and pleasure
Mingling toils with peace and rest

Abstract

Chromatographic purification is an integrated part of organic synthesis. The Dry Column Vacuum Chromatography presented here, has excellent resolving power, is easily applied to large scale chromatography (up to 100 g) and is fast. Furthermore, the technique is economical and environmentally friendly due to significant reductions in solvent and the amount of silica used. Therefore, it is an excellent alternative to the commonly used Flash Column Chromatography for purification in organic synthesis.
In our efforts to synthesise large quantities of the nucleoside analogue LNA,1,2 we regularly purify quantities of up to 100 g of highly functionalised nucleoside and carbohydrate derivatives. Conventional silica gel column chromatography techniques including Flash Column Chromatography3 afford poor separation of amounts exceeding 10 g demanding purification of the reaction mixtures after division into several minor batches. This is unfeasible due to the large quantities of silica gel, solvents and time required.
In our search for a simple and efficient method for large scale separation of complex mixtures, we re-discovered and further developed a technique first described by L. M. Harwood called “Dry Column” Flash Chromatography.4 This technique has mainly been used for small to medium scale purifications (< 2 g) with separation power rivalling that of analytical TLC. We have now adapted this technique to large scale chromatography (over 10 g compound mixture) without losing the excellent resolving power observed with smaller amounts on smaller columns. We have prepared and eluted large columns (diameter 10–13 cm) with up to 100 g of complex mixtures in 1–2 h depending on the number and size of the fractions collected, the efficiency of the pump and the kind of silica type used. We have chosen to name this improved version of Harwood’s technique Dry Column Vacuum Chromatography (DCVC) since “Flash” is misleading in this context.5
The general experimental setup suggested by the inventor4,6 and others7,8 consists of glassware found in any organic chemistry laboratory. However, the setup is not practical as it is necessary to disassemble it for each fraction (Figure 1), which is tedious and time consuming.
The setup is significantly improved by using an ordinary separatory funnel,9 an adapter with a sidearm and a three-way stopcock attached on the sidearm allowing one to let air into the funnel without turning the pump off (Figure 2a). The only drawback with this setup is that with large sintered glass funnels (diameter over 10 cm) it tends to get very high and as a consequence impractical. We have solved this problem by designing a compact vacuum proof receiver (Figure 2b). Our adaption of the experimental setup has significantly reduced the time required for DCVC and provides a construction that is easy to handle for large as well as small scale chromatography.
The experimental procedure can be summarised as follows (see experimental section for detailed procedure):
A sintered glass funnel of the appropriate size10 is filled with approximately 6–7 cm of loose silica and tapped to give a level surface.
Vacuum is applied and the surface is pressed firmly to give a completely level, well compacted bed approximately 4.5–5.5 cm high.
The column is checked for voids and channels by pouring n-heptane onto the silica bed while applying vacuum. If the column is packed properly, the solvent will descend in a horizontal line.
The mixture to be separated is dissolved in an appropriate low boiling solvent (eg. ethyl acetate, methanol) and pre-adsorbed on silica.11 The silica is added as a thin uniform layer on top of the column and step (2) is repeated.
The column is gradient eluted with a suitable solvent system and fractions are monitored by TLC.

Several problems can arise due to evaporation of solvents during chromatography. The most significant being difficulty in performing a controlled gradient elution and water condensing on the glassware. This can be prevented by avoiding volatile solvents such as diethyl ether, dichloromethane and pentane. Mixtures of n-heptane, ethyl acetate, and methanol are recommended as they are easy to handle and remove after separation has been accomplished.
Elution of compounds is usually accompanied by frothing on the underside of the sinter. As a rule of thumb, a compound will elute in the solvent mixture where the Rf value is ca. 0.5 on analytical TLC.
When chromatographing a mixture of compounds (approx. 20–50 g) with a ΔRf ~0.05 (by TLC) on a sintered glass funnel with a diameter of 10 cm, we usually collect 100 mL fractions by gradient elution. Normally this yields compounds that are >95% pure by HPLC. If a better separation is desired a different solvent gradient and collection of smaller fractions usually improve the result.
In order to obtain good separation, the choice of the correct silica type is essential. Resolution is determined by particle size. As a rough guide, reduced particle size gives better resolution. On the other hand, too small particles will result in an extremely compact column that elutes very slowly. According to the inventor6 and others,7 TLC silica without the gypsum binder (5–25 µm) should be used for DCVC because it is cheaper than the silica used for regular chromatography (e.g. Flash Column Chromatography) and because “regular” silica is too free flowing to allow easy column packing. This is also true in our hands for Merck Silica Gel 60 (40–63 µm) used for Flash Column Chromatography because the normal packing procedure does not yield a sufficiently compact column. As a result, the solvent just pours through the columns affording very poor separation. If the column is packed using a high vacuum pump, compact columns with good separation can be prepared. However, this approach is undesirable for several reasons, most of all because of the long time required to prepare such a column.
If Merck Silica Gel 60 (15–40 µm) is used, the problems are avoided. We have experienced no problems when using Merck Silica Gel 60 (15–40 µm) instead of TLC silica (5–25 µm) and in our hands the same time is needed to prepare a column with either type of silica. Although it is difficult to reproduce the exact chromatography conditions, the data suggest that TLC silica (5–25 µm) without the gypsum binder offers a slightly better separation compared to Merck Silica Gel 60 (15–40 µm) as expected due to smaller particle size. TLC silica (5–25 µm) is about 10–15% cheaper than Merck Silica Gel 60 (15–40 µm). Furthermore, a column packed with TLC silica (5–25 µm) requires approximately 10–15% less silica by mass compared to Merck 60 (15–40 µm). However, a column packed with TLC silica becomes very compact and therefore significantly slower in eluting.
Our preferred silica is Merck Silica Gel 60 (15–40 µm) as it offers excellent resolution and gives considerably faster eluting columns than those packed with TLC silica.
A typical example of a compound mixture that was separated successfully is shown in Figure 3. An analytical TLC of the compound mixture in 10% n-heptane, 90% ethyl acetate (v/v) showed 4 compounds with Rf values: 0.45 (1), 0.25 (2), 0.20 (3) and 0.10 (4). The compounds were successfully separated and isolated on a 10 g scale in 1.5 hours including packing of the column, elution and evaporation of the solvent fractions containing the pure compounds. The column (diameter 10 cm, height 5 cm, Merck silica gel 60, 15–40 µm) was eluted with 0–100% ethyl acetate in n-heptane (v/v) with 5% increments in ethyl acetate concentration for each fraction collected (twenty-one 100 mL fractions). After isolation, the identity of the compounds depicted below was established by NMR. The desired compound 2 was isolated in 98+% purity by HPLC and 1H-NMR.
In conclusion, DCVC provides a robust, fast and economical method for large as well as small scale separations. In addition, the technique is superior in resolution power to Flash Column Chromatography because of the reduced diffusion during chromatographic separation. This means that each compound elutes in fewer fractions and that less cross contamination of fractions is observed.
We have used Dry Column Vacuum Chromatography for purification of a wide range of complex mixtures comprising highly functionalised nucleosides and carbohydrates with excellent results. It is possible to perform DCVC using mixtures of nonchlorinated, nonvolatile solvents such as n-heptane, ethyl acetate and methanol. This and the greatly reduced amount of silica used compared to other techniques reduces the enviromental impact of the process. Separation of compounds with ΔRf ~0.05 (by analytical TLC) should at least be expected, but with experience separations as efficient as those with analytical TLC can be achieved.
Chromatography equipment was assembled as depicted in Figure 2a or 2b. Analytical TLC was performed using Merck 5554 silica 60 aluminum sheets. The silica used for DCVC was Merck 15111 silica gel 60 (15–40 µm) and Merck 9385 silica gel 60 (40-63 µm) purchased from Merck Eurolab. TLC silica without binder (5-25 µm) was purchased from Sigma-Aldrich Denmark. Solvents were HPLC grade from LABSCAN. Vacuum was applied with a Vacuubrand MZ 2C diaphragm vacuum pump (1.7 m3/h, 10 mbar) instead of a water aspirator for enviromental reasons. Sintered glass funnels (porosity 3) with diameters up to 17 cm are commercially available.

Dry Column Vacuum Chromatography
Column Packing: As a rough guide, 1 cm2 of silica surface can be charged with up to approx. 500 mg of compound mixture. However, the sample size per cm2 can be increased substantially if less resolution is required. The glass funnel should be at least 7 cm from the sinter to the lip allowing each solvent fraction to be added in one batch instead of slowly being poured onto the surface of the silica. A cylindrical sintered glass funnel (porosity 3) is filled with 6–7 cm of loose Merck 15111 silica gel 60 (15–40 µm) and then tapped to give a level surface of silica. The glass funnel is placed in a Buchner flask and vacuum is applied. The silica is pressed firmly with a flat object (eg. glass or rubber stopper) to give a flat, well compacted silica column approx. 4.5-5.5 cm high. Special care should be taken to compress the silica at the circumference of the glass funnel with a spatula. The column is checked for voids and channels by pouring n-heptane onto the surface (protected by filter paper) while applying vacuum. If the column has been properly prepared, the solvent will descend in a horizontal line. If this is not the case, the column must be sucked dry and the above packing procedure repeated. With acid sensitive compounds, the silica can be pre-treated with a mixture of 1-5% Et3N, n-heptane (v/v) during the packing procedure.
In our experience, columns higher than approx. 4.5-5.5 cm do not improve resolution and shorter columns should be avoided because of significantly reduced separation power. Short columns (app. 1-3 cm high) can be quite good for very simple separations but truly provides more of a filtration than an actual chromatography step.
Sample Application: While preparing the column, the compound mixture should be pre-adsorbed on Merck silica gel 60 (15–40 µm).11 The mixture is dissolved in a small volume using an appropriate solvent (e.g. mixtures of EtOAc and MeOH) and the silica is added. To obtain optimal separation it is desirable to apply the sample on the column in as thin a layer as possible. For this reason, no more than ca. 1:1 (w/w) silica should be used for pre-adsorbtion. The solvent is removed from the slurry under reduced pressure on a rotary evaporator. A splashguard should be used since silica has a tendency to bump when it is almost dry. The slurry should not be evaporated to complete dryness in a single step since this may result in a hard crust. Instead the silica should be scraped down the sides of the flask before the last solvent has been removed (if a coarse type of silica is used for pre-adsorption it is most easily removed from the flask). When the silica is dry, it is transferred to a mortar and ground to give a fine powder that is added in a thin uniform layer on top of the column. Vacuum is applied and the surface is pressed firmly as in the column packing step.
Solvent System: The column is developed by gradient elution using a suitable solvent system. For most separations, mixtures of n-heptane, EtOAc and MeOH are excellent. The least polar solvent mixture is added first followed by solvent fractions typically with 1-10% increments in the most polar component. Our preferred solvent system for most separations is 0-100% EtOAc in n-heptane (v/v) - with increments of 5%. For very polar mixtures, it is preferable to start in a more polar solvent mixture of n-heptane, EtOAc and shift to solvent mixtures of EtOAc, MeOH when 100% EtOAc is reached.
Elution: When the solvent system has been decided, vacuum is applied to the column. The first solvent fraction is poured on the filter paper protected surface of the column. While the fraction is eluting the next fraction is prepared. The solvent fractions should not be prepared beforehand as this is too time consuming and evaporation can result in poor gradient elution. The first solvent fractions are usually lost due to adsorption on the silica. When the fraction has been sucked through the column (i.e. the solvent is dripping slowly from the column), air is allowed into the setup by turning the three-way stopcock (Figure 2) and the solvent fraction is collected. Vacuum is applied again and the next solvent fraction is poured onto the surface of the column. Elution of compounds is monitored by TLC.
As a rule of thumb, compounds will elute in the solvent mixture where they have an Rf value of approximately 0.5 on analytical TLC. Elution of compounds often co-occurs with frothing on the underside of the sinter. The size of the fractions and the increase of the more polar component in the solvent system varies with the desired separation. Smaller fractions and a slow increase in polarity improves the resolution significantly but also takes considerably longer time.
Although we have never experienced any problems, it is important to use precaution with evacuated glassware. Special care should be taken when using a separatory funnel as it is not designed for this purpose. All chromatography should be performed in a hood behind a safety shield.
In general we have found that it is possible to load a mixture of up to approx. 500 mg on 1 cm2 of silica surface (e.g. approx. 40 g on a column with a diameter of 10 cm) and still achieve good separation of mixtures with a ΔRf - 0.05 (by analytical TLC).
For small columns (<4 cm) it is usually easier to dissolve the mixture in a small volume of n-heptane and add it evenly onto the surface of the column with a pipette. If necessary a small amount of EtOAc can be added to dissolve more polar compounds. If the mixture is very polar, the pre-adsorbtion procedure is preferable as the use of too much EtOAc will compromise the resolution.

Bagaimana dengan Mereka?

Dalam hidup ini dapatkah kita berhenti memikirkan kebenaran? Tentang fakta, peristiwa, serta realita yang terjadi pada diri seseorang? Seringkali pertanyaan ini muncul saat kita sedang mengalami suatu kasus atau permasalahan yang menuntut kita untuk memikirkannya kembali. Dan kita hanya bisa membisu atas semua yang telah terjadi tanpa dapat melakukan sesuatu yang berarti bagaikan seorang bayi yang tak berdaya. Dengan segala keamanan dan kenyamanan hidup, kita telah membutakan diri kita sendiri. Padahal di balik itu semua pernahkah kita memikirkan bagaimana dengan mereka yang menjadi korban atas fakta, peristiwa, dan realita yang dengan terpaksa harus mereka terima karna ketidakberdayaan mereka? Siapakah yang mau peduli dengan nasib mereka yang tanpa pamrih menolong mereka untuk bisa keluar dari kepahitan hidup?
Pernah di suatu malam yang dingin kulihat di perempatan jalan itu, beberapa anak kecil tidur di trotoar pinggir jalan dengan beralaskan tubuh mereka. Peristiwa ini bukanlah peristiwa pertama yang kulihat tapi telah berkali-kali aku melihatnya di tempat yang sama pula. Apakah benar trotoar itu adalah tempat yang harus mereka tempati untuk melewati malam dingin yang menusuk ke dalam tulang? Satu yang ingin aku tanyakan pernahkah kalian bayangkan apa yang akan terjadi dengan tubuh kecil dan rentan mereka beberapa tahun mendatang? Kerapkali kucoba untuk membayangkannya namun begitu aku mulai memikirkan yang muncul justru banyak pertanyaan yang aku sendiri tidak tahu apa jawabannya. Sebenarnya dimana rumah mereka? Haruskah mereka tidur di malam yamg dingin itu hanya dengan beralaskan tubuh kecil dan rentan mereka? Apa yang sedang dilakukan orang tua mereka sehingga mereka membiarkan anak mereka harus tidur di jalanan? Apakah besok mereka tidak sekolah? Bagaimana jika mereka sakit? Dan akhir dari seluruh pertanyaan yang muncul adalah siapakah yang seharusnya bertanggung jawab atas segala fakta yang terjadi ini?
Dan satu hal yang dapat aku pelajari dari realita ini adalah bahwa kita tidak harus mencari tahu siapa yang seharusnya bertanggung jawab atau siapa yang benar atau salah atas semua ini tapi bagaimana dengan diri kita sendiri. Apakah kita telah membuat mulut kita bicara untuk berani mengatakan kebenaran ataukah kita telah membuat mata kita terbuka untuk melihat keadaan orang lain di tengah segala kenikmatan hidup yang kita miliki? Atau apa yang dapat kita lakukan sehingga mereka dapat merasakan bahwa ternyata di tengah-tengah kepahitan, mereka masih dapat merasakan sesuatu yang manis yang mungkin dapat dijadikan kenangan terindah dalam hidup mereka.
Hal terpenting yang dapat aku pelajari adalah bahwa inilah hidup. Hidup bagaikan dua sisi mata koin yang tidak dapat dipisahkan di satu sisi dapat terasa pahit namun di sisi lain dapat memberikan rasa manis. Tapi biarlah hidup itu berjalan sesuai dengan apa yang telah direncanakan oleh Dia, Sumber Kehidupan. Manusia hanya berusaha untuk melakukan yang terbaik sesuai dengan porsi masing-masing. Selain itu semua, kepedulian kita terhadap sesama sangat dibutuhkan dalam menjalani kehidupan ini sehingga tidak terjadi kesenjangan dalam hidup.
Ingin rasanya aku merengkuh tangan mereka dan memeluk mereka agar aku bisa merasakan apa yang sebenarnya sedang mereka rasakan saat itu. Aku bisa berbagi dengan mereka meski aku sadar bahwa apa yang kulakukan mungkin tidak dapat menolong mereka untuk keluar dari masalah yang mereka alami. Tapi..... aku mau belajar agar aku dapat merendahkan diriku sehingga semua kenikmatan hidup yang telah Ia berikan tidak membuatku menjadi orang yang buta dan bisu.

Hari terakhirku ngajar mereka....
Sehari dah lewat.... Tapi, kenapa ya aku koq kangen banget ma mereka??

Mereka itu murid2 lesku.. Yah, meskipun kadang2 mereka nyebelin tapi aku care banget ma mereka.... Hari ini aku bingung banget nih mo ngapain padahal tugasku lagi banyak2nya tapi g tau kenapa ya koq rasanya males banget buat kerjainnya... Beda banget kalo aku ngajar mereka setiap hari meskipun cape' tapi aku seneng koq...

Yah meski kadang mereka bikin aku kesel tapi dari mereka aku belajar banyak hal like kepolosan mereka, omelan2 kecil mereka yang benernya adalah perhatian mereka buat aku yang pelupa, cuek, n kadang2 g peka ma keadaan mereka hari itu....

Tapi aku juga berharap semoga aku bisa berguna buat mereka n nantinya mereka bisa jadi orang yang berguna juga buat orang lain, buat temen2 mereka n buat setiap orang yang ada di sekitar mereka.... Dan satu hal yang paling penting mereka bisa jadi berkat.. Cuma itu harapanku buat mereka... Good Luck 4 You, My lovely students...

Ya udah deh...
To all my students Happy Holiday ya....
See you next month!!!!

Gimana Nih??????

Duh gimana y???

Perasaan itu muncul lagi nih......
Aku mulai bingung lagi lho!!!! Yakin ga ya ma pilihanku ambil jurusan ini?????
Kata seseorang "aku tu mesti cari tau dulu akar masalahnya apa?" tapi sampe sekarang aku masih belum tahu......

Gimana ya???? Lanjutin g???

Kalo g dilanjutin sayang tapi.....
Kalo dilanjutin.....
Ntar kalo salah????

Ya udah deh pasarahin semuanya aja deh.....
yang penting jalanin yang ada aja sekarang dan nikmatin semuanya.....

Ngomong2 kamu tau g kalo Jumat lalu tepatnya tanggal 23 Mei tu hari yang paling bikin aku trauma lho!!!!
Pagi itu waktu aku mp berangkat kuliah eh di tengah jalan malah terjadi kecelakaan n nabrak motor....Alhasil kakiku sekarang mesti d perban deh!!!! Belum lagi g isa nyetir n sekarang aku jadi rada takut nih kalo nyetir d jalan yang rame padahal..... biasanya aku dijulukin pembalap lho ma temen2 yang laen.....
Jadi takut juga neh....

Tapi ku berharap semoga dengan berjalanny waktu trauma itu bakalan ilang dengan sendirinya deh.......

Tapi hari ini aku da mulai coba nyetir lagi lho!!!! Hehehehe....
Rada takut sih tapi mo gimana lagi kalo g kaya gitu ntar traumanya g ilang2 trus ntar malah ngerepoti pa2 lagi mesti nganter jemput.... Pa, sory ya seminggu ini da bikin pa2 tambah repot mesti bolak balik kantor buat anter jemput aku....

Dah dulu deh buat hari ini sekarang aku mesti tideur cz besok pagi ada pelayanan ibadah pagi neh.....

Bye....
