Mixtures of alcohols are rarely analyzed directly by gas chromatography. Instead, the mixtures are first allowed to react with trimethyl chlorosilane (TMS-Cl) to gives a TMS ether mixture plus HCl as a side product . Why is such derivatization typically performed? What sort of GC detector would be best for such determinations if linear Dynamic range is important 高手們~請幫幫我了 感激不盡 --
