How to calculate qc chem
WebOnce we’ve dried down, reconstituted, and analyzed our post and pre-spikes via LC/MS-MS, we can then calculate how much of compound X we were able to extract by calculating the percent recovery of compound X (Equation. 1). Equation 1. % Recovery = [ (Peak Area of Pre-Spike) / (Average Peak Area of n Post-Spikes, where n ≥ 3)] X 100. WebRepetitive testing of the control material yields the mean and the standard deviation. The current recommendations (according to the CLSI 24-A3 guidelines) are to measure the …
