The art of adding confidence to laboratory measurement system

摘要

In order to generate valid data from the test equipments many techniques are practised.Out of them,the calibration technique is one of the best techniques for ascertaining the generation of quality data from the instrument.But sometimes in some experiments the frequency of calibration is such that as if it needs calibration at every work session.For those cases judging quality of the equipment is essential for good laboratory practices (GLP).
