一种新型的通用型检测器——电喷雾检测器

摘要

本文重点介绍了新一代通用型检测器电喷雾检测器（CAD）的仪器结构、工作原理、性能特点、实际应用以及与其他通用型检测器的优势对比。CAD作为一款质量敏感型检测器,其响应值只与进样质量有关,不依赖于化合物的结构与性质,可检测所有非挥发性化合物和部分半挥发性化合物。检测范围宽,灵敏度高,重现性好,是紫外和质谱检测器的有力补充。%This paper introduces a new generation of universal detector Corona Charged Aerosol Detector（CAD） including its instrument structure,working principle,characteristics,practical application and the advantage compare with other universal detectors.CAD as a quality sensitive type detector,the response is only related to the quality of the sample,not dependent on the structure and the property of the compound,and it can detect all non-volatile compounds and many semi volatile compounds,wide range detection,high sensitivity,good reproducibility and can serve as a vigorous complementarity to ultraviolet detector and mass spectrometry detector.
