摘要

建立了流动相不添加添加剂的液相色谱-常压化学电离(APCI)-质谱联用法测定两种苯脲类除草剂及其降解产物的方法。当汽化器温度为250℃,选择正离子检测模式时,APCI检测灵敏度最大。在此条件下,总离子监测和选择离子监测的检出限(S/N = 3)分别为2.5 ~ 3.0 ng和0.12 ~ 0.26 ng。在diuron的生物降解性测试中,可以通过所提出的方法确定少量降解产物。

Liquid chromatography–mass spectrometric analysis of phenylurea herbicides and their degradation products using an atmospheric pressure ionization interface
A method was developed for the determination of two phenylurea herbicides and their degradation products using liquid chromatography–atmospheric pressure chemical ionization (APCI)-mass spectrometry without any additives in the mobile phase. The APCI detection sensitivity of these compounds was maximized when the vaporizer temperature was set at 250 °C and a positive-ion detection mode was chosen. Under these conditions, the detection limits (S/N = 3) of these compounds in total-ion and selected-ion monitoring were 2.5–3.0 and 0.12–0.26 ng, respectively. In a biodegradability test on diuron, small quantities of degradation products could be determined by the proposed method.
