色谱法是目前应用最广泛的分析测试技术之一。长期以来,不同领域的分析测试人员针对色谱分析的检出限、定量下限等的概念、估算方法及其在各自领域的应用等方面进行了广泛的探讨[1,2]。在职业卫生检测规范中,对样品测定时譬如检出限和定量下限等指标没有做统一的规定;作者在长期的职 Chromatography is currently one of the most widely used analytical test techniques. For a long time, analytical testers in different fields have conducted extensive research on the concepts of detection limit, quantitative lower limit of chromatography, estimation methods and their applications in their fields [1,2]. In occupational health testing norms, the determination of the sample, such as the detection limit and lower limit of quantitative indicators such as no uniform provisions; the author in the long-term
