Tar éis scaradh, caith amach an tsraith uisciúil agus nigh an tuaslagán beinséine le 100 ml uisce go dtí nach aigéad an tuaslagán a thuilleadh.
After separation, discard the aqueous layer and wash the benzene solution with 100 ml of water until the solution is no longer acid.
Lig dó socrú i suíomh cothrom agus ansin forchisealaigh le cainníocht den mheán (4.2.2.) arna ionaclú amhail mar atá i bpointe 8.1 chun ciseal 1 mm ar tiús (30 ml i gcás pláta de thrastomhas 200 mm) a thabhairt.
Allow to set in a level position and then over-layer with a quantity of the medium (4.2.2) inoculated as in point 8.1 to give a layer 1 mm thick (30 ml for a plate of 200 mm diameter).
Tiubhaítear an t-úsc agus scartar é trí chrómatagrafaíocht cisil thanaí ag baint úsáid as glóthach shilice.
The extract is concentrated and separated by thin layer chromatography using silica gel.
