Samples are mytilus (bivalve). Extracts eluted with F1(hexane) F2 (hexane-Dichloromethane) and F3 (Dichloromethane). All fractions combined in extraction flask. After florisil column some of extract colours are brown or light brown, I used H2SO4 and the colour didn't change. I will inject to GC-MS but before injecting how can I remove the clour?
Thanks for all,
