4 principle of the method

Electron capture detector is an ionization detector, with high selectivity and sensitivity, only for substances with a negative electrical properties, such as those containing

Halogen, sulfur, phosphorus, nitrogen substances responding. Pesticide residues pesticide content analysis of key features compound index. Traces of pesticide residues

After concentrated by gas chromatography - electron capture detector was used to detect, and the chromatograms corresponding data record by a data processing system.
