no one will raise the question on analysis of samples on
the instrument which fails in calibration.

Answer / k l reddy
Need not to analyze all previous batches but you should
analyze 6 previous batches(recent batches of before
calibration)on different system(which is qualified) and
compare the results with old results. Fallow the same
prociser until the resukts matched with old results.
