Pyrolytic Esterification Derivatization Chemistry for the Qualitative Determination of Sulfonate Surfactants and Indirect Detection of Sulfate Surfactants through On-Line Degradation Products for Gas Chromatography-Mass Spectrometry

Autor: Igwebuike, Alexander

Sulfonate surfactants are too polar to be directly determined by gas chromatography (GC) and so derivatization chemistry (sulfonyl chloride formation, silylation and pyrolytic methylation) of these analytes is necessary. Pyrolytic methylation, rarely
