3 Terms and Definitions
GB/T 3359 and JJF1001 defined in the following terms and definitions, symbols apply to this document.
3.1 Laboratory detection limit InterlaboratoryDetectionEstimate
IDE The minimum concentration can be detected with high probability, i.e., at 90% confidence level, the ratio of the concentration of the sample is detected by the IDE Laboratory
95%, the proportion of the sample concentration is 0 is not detected in laboratory was 99%.
3.2 Interlaboratory limit of quantification InterlaboratoryQuantitationEstimate
IQE RSD is equal to Z% minimum concentration corresponding.
3.3 Interlaboratory Pro boundaries InterlaboratoryCriticalLimit
ICL At 90% confidence level, the ratio of the concentration of the sample is not detected correctly 0 laboratory was 99%.
3.4 Experimental standard deviation
Standard deviation standarddeviation
The same is measured n times measurement, characterization measurements of the amount of dispersion.
Note 1. n measurements of a single measured value xk experimental standard deviation s (xk) according to Bessel formula.
s (xk) = i = 1 (Xi-x) 2 n-1
