Webexperimental design chosen by the applicant during method testing and optimization; the same evidence should be provided in case of methods intended for validation as … The limit of quantification (LoQ, or LOQ) is the lowest value of a signal (or concentration, activity, response...) that can be quantified with acceptable precision and accuracy. The LoQ is the limit at which the difference between two distinct signals / values can be discerned with a reasonable certainty, i.e., when the signal is statistically different from the background. The LoQ may be drastically different between laboratories, so another detection limit is commonly u…

Webquantification limit (LOQ).13 In this study, the baseline noise was first determined by measuring the peak-to-peak noise in a representative 1 min segment of the baseline where no peaks elute, but close to the peak of interest. The signal was determined from the average height of three injections of nitrite standard (1 µg/L). WebLoQ is also used for two purposes: (a) to determine whether the measured concentration of the sample is in the range that allows it to be quantified with fit for purpose accuracy with the given analytical method, and (b) to characterize the analytical method. When estimating LoQ, the data used to estimate it should be in the range of LoQ.
