This one is canonical, and it is the first ever Flash Chromat video I have ever watched, and I review it every time I want to synthesis something.

It's 2020 now, and this video is superb! Now I can make my own silica column.

These instructions are for organic chemicals but this can also be done on inorganic chemicals but your solvents will be much more polar, probably water or water with a little acid or base. Some elements have properties so similar they are had to separate, a classic example being lanthanides. In fact lanthanides sold commercially are often mixtures because of practicality. Fractional crystallization of bromates was one of the methods used historically to separate lanthanides. What was thought to be one element resolved into two or more. Practical use was almost entirety with mixtures. Then it was discovered that they could be separated with column chromatography. This was eventually done on a large scale.

Thank you so much. Is there standard to use silica gel in column, I mean if my sample a little bit like (0.01 gram), how much of silica gel use here? in contrast, if I have a lot of samples such as (1 gram or more), here, how much of silica gel have to use? I mean is there ratio from silica gel to sample to use in column, please tell me. thank u in advance

happy new year Dr. please I need your help .If I used wet packing of silica gel to column (slurry), here, can I use any solvent for silica gel until reached slurried, or must use only hexane. thank you
