前言平时人们常说“灵敏度高的分析方法”和高灵敏度分析”这两句话,我们自己也常这样说。这里所说的“高灵敏度”意味着能够检测出极低浓度或者极少量的欲测物质,同时也意味着检出限低。可是,实际上灵敏度(Senstivity)和检出限(Limit ofdetection)这两个术语的含意是不同的,灵敏度高而检出限并不一定低。很早以前人们就使用“灵敏度”和“检出限”这两个术语,但是把它们作为正式术语予以确切定义却 Foreword Usually we often say “high sensitivity analysis method” and “high sensitivity analysis”, we often say the same. “High sensitivity” here means that it can detect very low concentration or a very small amount of desire Test substances, but also means that the detection limit is low, but in fact the sensitivity (Senstivity) and the Limit of detection of the two terms mean different, high sensitivity and the detection limit is not necessarily low. People used the terms “sensitivity” and “detection limit” long before, but defined them as formal terms
