Dear Members,
In BA/BE study bio-analysis, is high internal standard response variability is a cause for LC-MS data batch rejection? (for example more than 20% of the unknown samples showing more than ±50% difference etc..)
General practice is only one scenario is considered for IS variation (±50% difference from the mean), is there any other scenario to be considered?
Trend analysis for Internal standard area response? Please comment.
Thanks & regards,
Avinash Jain M V

(or even simple ones), we must try to free our minds of dogma and
to guarantee the freedom to publish, to contradict, and to experiment.
