Calibration Verification and Linearity: Regulatory Requirements

Nettetlinearity: ( lin'ē-ar'ĭ-tē ), A relationship between two quantities whereby a change in one causes a directly proportional change in the other. [L. linearis, linear, fr. linea, line] NettetLinearity of dilution refers to the extent in which a spike or natural sample’s (in a particular diluent) dose response is linear and in the desired assay range. Spike and recovery and linearity of dilution are related. Experiments can be designed to test both simultaneously.

NettetPhotometric linearity is a measure of the linearity of the measured values (e.g. absorbance) as a function of increasing concentration. This is especially important for quantitative applications. Photometric linearity can be determined with the same procedures and filters used to determine photometric accuracy, however, at three … NettetLOQ) in another laboratory. Whichever approach is used the laboratory must ensure that it allows them to demonstrate that their method is fit for purpose. 2.6.2 Use of correction factors for calibration curves The use of calibration curves prepared in procedural blanks, rather than matrix, followed by

NettetThe LOD varies from 0.4 to 5.0% of the DON cutoff value for each drug. The limit of quantitation (LOQ) is calculated as the LOD + 7 SD. The range for LOL is greater for drugs analyzed with deuterated internal standards compared with those using conventional internal standards. For THC acid, cocaine, PCP, and morphine, LOLs are 8 to 160-fold ... NettetLinearity, together with some natural continuity properties and normalization for a certain class of "simple" functions, may be used to give an alternative definition of the integral. This is the approach of Daniell for the case of real-valued functions on a set X , generalized by Nicolas Bourbaki to functions with values in a locally compact …
