GC DERIVATISATION REAGENTS

             

A large number of reagents are used to prepare derivatives for gas chromatography, but most of the derivatization reactions fit into one of three categories: acylation, alkylation, or silylation. This bulletin describes each category, and presents information on how to choose the proper reagent based on the functional group(s) of the compound to be derivatized.

 

An extensive range of Derivitisation Reagents are available from Sigma Aldrich and Macherey-Nagel.   If you do not see the reagent you are looking for please email sales@greyhoundchrom.com  We will be happy to source it for you.
