Method loq
Webdetection）或定量限（LOQ, limit of quantification）表示。 检测限（LOD）指由基质空白所产生的仪器背景信号的3倍值的相应 量，或者以基质空白产生的背景信号平均值加上3倍的均数标准差。 定量限（LOQ）指由基质空白所产生的仪器背景信号的10倍值的相应 WebImportant aspects of LoQ estimation •LoQ is used for: 1. Is the sample concentration high enough for “fit for purpose” quantitation? 2. To characterize the analytical method •The used LoQ estimation approach must be stated •When estimating LoQ: •Use data in range of LoQ •Use matrix matching samples
