Derivatization reagents for Gas Chromatography

イメージ Gas chromatography / mass spectrometer (GC / MS) has been popularized in recent years though, in order to perform the analysis effectively, the samples must be derivatized.
We offer a line-up of derivatization reagents such as silylating agent, acylating agent, alkylating agent and esterifying agent, etc..
