Exploring the Factors Affecting the Degradation of Endrin in Gas Chromatography
Endrin is one of the common organochlorine pesticides.In this paper,gas chromatography(GC-ECD)was used to investigate the factors affecting the degradation of endrin.It was determined that in the pulse non split injection mode,when the injection port temperature was 280℃,the preferred choice was the ultra-high inert glass fiber liner 5190-2293 and non adhesive loss and temperature optimized BTO spacer 5183-4757.The degradation rate of the standard sample of endrin was the lowest,but after 10 consecutive injections,the degradation rate no longer met the instrument performance inspection requirements specified in the standard.
