Method for rapidly detecting paraquat in biological matrix sample

The invention discloses a method for rapidly detecting paraquat in a biological matrix sample, which uses a real-time direct analysis ion source and a mass spectrometer for detection, does not treat the detected biological matrix sample, and is an in-situ detection method. Pretreatment of traditional means is omitted, and rapid and real-time detection of biological matrix samples poisoned by paraquat is achieved. 本发明公开了一种快速检测生物基质样品中百草枯的方法，使用实时直接分析离子源和质谱仪进行检测，不存在对检测生物基质样品进行处理，为原位检测的方法。节省了传统手段的前处理，并对百草枯中毒的生物基质样品实现了快速和实时检测。
