摘要：

Gas chromatography injection port thermal decomposition of chlorsulfuron resulted in two volatile decomposition products (2-amino-4-methoxy-6-methyl-1,3,5-triazine and 2-chlorobenzenesulfonamide) which were characterized by gas chromatography and gas chromatography-mass spectrometry. Quantitation of chlorsulfuron as its volatile thermal decomposition product 2-amino-4-methoxy-6-methyl-1,3,5-triazine was accomplished by gas chromatography-nitrogen-phosphorus detection analysis and the linearity of standard curves so obtained was independent of injection volume (0.5-3 μl) and injection port temperature (230-270°C) for the concentration range examined (62.5-1000 ng/ml). © 1990.
