What is recovery in a chemical analysis as lc-ms/ms?

Recovery. According to FDA Guidelines [16] for bioanalytical method validation, the recovery of an analyte is the detector response obtained from an amount of the analyte added to and extracted from the biological matrix, compared to the detector response obtained for the true concentration of the analyte in solvent.

To calculate % recovery divide the obtained (quantified by LC-MS) concentration of your analyte in the solution (you need a calibration) by the value of expected"" ·" : "It depends. If you have a step that may lead to incomplete sample analysis, such as an extraction

Calculating matrix effect, recovery and process efficiency From this definition, though most often used in the LC-MS literature, some with F- and t-test or ANOVA to evaluate the statistical significance of the obtained matrix effect values.
