Hi! I'm Prisca, a student in Singapore. I'm doing my final year project now and is urgently seeking help in the pretreatment of samples before starting GC. How do we carry out derivatization of thiamin tablets before starting GC? Is silication a way to do so?? If that's the way, what is the procedure to carry it out? Apart from silication, are there any other methods to do so?? To those out there who know the answer, please sent me help as fast as possible as this is really urgent.
