| Abstract: | A method using derivative gas chromatography-negative chemical ionization was established to determine herbicide containing chlorinated acid herbicide in water. This essay analyzes the main elements of herbicide containing chlorinated acid herbicide gas chromatography with derivation from four aspects: the first aspect is to chose and decide extraction model, extraction solvents, acidity, concentration, etc,according to different requirements; second is to compare different derivative methods and analyze the necessity of subsidiary conditions; third is to choose different Ion Source subject to relevant derived products; fourth is the rational use of standard reference materials. |
