While this question has been asked and answered, it may indicate that a column chromatography qualitatively is possible. At home, is it possible after collecting silica gels from small bags of them from snack packages? Secondly, if qualitative analysis is possible, how about quantitative?

    $\begingroup$ The type of silica that's used for flash chromatography is a very specific one, in particular the particle size is very important (see this one for instance). I would be very surprised if the one from snack packages were the same grade. And BTW it's really not healthy to inhale it, so I'd definitely not use it at home / without proper equipment like a fume hood. $\endgroup$ Mar 24, 2021 at 17:10

    $\begingroup$ Silica gel from snack packages does not even look like what you need for chromatography, not even remotely. $\endgroup$ Mar 24, 2021 at 18:23

    $\begingroup$ Silica gel from snack packages are designed to absorb moisture from atmosphere. Silica gel used in laboratories have designed to separate compounds according to their polarities, etc. using a mobile phase. This same thing Ivan Neretin has said in one sentence. :-) $\endgroup$ Mar 24, 2021 at 19:09
