The suitability of alkylbis(trifluoromethyl)phosphine sulphides for use as universal retention-index standards has been confirmed. In routine work, the M series were detected at the level of 0.4-0.6 pmol with flame ionization detection (FID), 2-7 fmol with alkaline thermionization detection (ATD) and 3-5 fmol with electron-capture detection (ECD). The sensitivities of ATD and ECD are so much greater than that of FID that their simultaneous use with FID is not possible. The sensitivities of ECD and ATD are similar enough that parallel use is possible. Examples of two-channel retention-index monitoring of pesticides from real samples are given.
烷基双(三氟甲基)硫化膦作为通用保留指数标准物的适用性已得到证实。在常规工作中,采用火焰离子化检测(FID)时,M系列的检测限为0.4 - 0.6皮摩尔;采用碱性热离子化检测(ATD)时为2 - 7飞摩尔;采用电子捕获检测(ECD)时为3 - 5飞摩尔。ATD和ECD的灵敏度比FID高得多,因此无法与FID同时使用。ECD和ATD的灵敏度足够相似,可以并行使用。文中给出了实际样品中农药双通道保留指数监测的示例。
