Nitrogen chemiluminescence detection(NCD) is a nitrogen-specific detector that responds to ammonia,hydrazine,hydrogen cyanide,and NO.A determination method of prometryn in vetiver grass and water was constructed using GC-NCD.The analytic procedure was based on conventional extraction,NCD was controlled by a Dual Plasma Burner and Controller,split injection mode at 1018℃ pyrolysis was chosen through optimizing.
