Why Use Signal-To-Noise As a Measure of MS Performance When It Is Often Meaningless?
May 1st 2011Signal-to-noise of a chromatographic peak from a single measurement has been used determine the performance of two different MS systems, but this parameter can no longer be universally applied and often fails to provide meaningful estimates of the instrument detection limits (IDL).
Single Multipoint Calibration Curve for Discovery Bioanalysis
May 1st 2011A single calibration curve run with staggered calibrants bracketing the unknowns is compared to running complete duplicate calibration curves, one at the beginning and one at the end of unknown sample analysis in an effort to accelerate discovery bioanalysis.
