Attempts at small-scale LC

Using some silica, mixed (mostly failed) results:
- Making a slurry first is a better way to get packing
- Small tubes are cool but tricky in that any air bubbles above the column are hard to clear and tend to mess things up
- Need 10-20X column volume at least, so smaller is better re: solvent waste
- Pushing air through was always bad
- I had channeling issues in general, and edge seepage (made up term?) in the thin column, maybe because flexible tube under pressure?
- Solvent messing: mineral spirits with variable ethyl acetate, then tested with water for things where I was worried about getting sprayed haha
- bibilous paper as filter seemed to work OK, for bigger one I used miniprep column.
- TODO hook up a fluorescent readout once spec arrives, try on TLC plates and pick a nice model system + solvent mix, try a scaled up one and get used to 10s of mls of solvent rather than being stingy
