核離子計數(shù)檢測器(NQAD)是一種新型的通用型高效檢測器,基于水凝粒子計數(shù)專利技術和氣溶膠原理,操作簡單,具有較高的信噪比和靈敏度,檢測范圍廣,重復性和穩(wěn)定性好,可以檢測到納克級水平。該檢測器適用于幾乎所有物質(揮發(fā)性物質除外),檢測藥物一般不需要衍生化處理,準確度較高。介紹其在抗生素類、糖類、離子類、酸類、聚合物類、皂苷類、甾醇類、脂類和環(huán)胺類等化合物分析中的應用。

Nano quantity analyte dectecor (NQAD) is a new general detector, which is based on the patented technology of water condensation particle counting and aerosol principle. Therefore, some advantages can be achieved such as simple and reliable operation, high signal-to-noise ratio and sensitivity, wide range of detection, excellent precision and stability, and the detection of ng level. The detector is suitable for almost all substances except volatile ones, which does not need derivative processing and has high degree of accuracy. The application of nano quantity analyte detector in analysis of antibiotics, sugar, ions, acids, polymers, saponins, lipids, sterols, and heterocyclic amines are introduced.
