Meet other people who like and understand what you do
I highlighted the most important part (for me), because I have always problems to [...]

Thin layer chromatography

August 12, 2009

Thin layer chromatography is probably the easiest way how to perform chromatographic separation. At least you do not need any instrument. In thin layer chromatography (TLC) the solvent flows through the stationary phase which covers the thin plate. One part of plate is submerged into the mobile phase which travel across the plate using [...]
