3 Terms and Definitions

The terms and definitions defined in GB/T 4146 (all parts) and GB/T 27417-2017 apply to this document. 3.1 limit of detection limit of detection; LOD The measured value obtained by a given measurement procedure has a misjudgment probability of β for the absence of a certain component in the substance, and a misjudgment probability for the presence of a certain component in the substance. The misjudgment probability of this component is α. The detection limit refers to the lowest amount of the analyte in the sample that can be detected, but it does not necessarily have to be accurately quantified. Note 1.The International Union of Theoretical and Applied Chemistry (IUPAC) recommends the default value of α and β to be 0.05. Note 2.The detection limit is often divided into two types, method detection limit and instrument detection limit. [Source. GB/T 27417-2017, 3.13, modified] 3.2 limit of quantitation; LOQ The lowest concentration or lowest amount of the measured component in the sample that can be quantitatively determined, and the analysis results at this time should be able to ensure a certain degree of correctness and precision. density. The limit of quantification is the lowest amount of the analyte in the sample that can be quantitatively determined, and the determination results have certain accuracy and precision. [Source.
