A REVIEW ON CALIBRATION OF ANALYTICAL INSTRUMENTS

Abstract

Author(s): CH. Aparna and D. Gowrisankar

Instrument calibration is one of the primary processes used to maintain instrument accuracy.
Calibration is the process of configuring an instrument to provide a result for a sample within an
acceptable range. There are three main reasons for having instruments calibrated are to ensure
readings from an instrument are consistent with other measurements, to determine the accuracy of
the instrument readings, to establish the reliability of the instrument i.e. that it can be trusted. This
review includes the information about the tests conducted for calibrating different analytical
instruments and acceptance criteria. Out of calibration is the major thing during analysis. It gives in
detail about the out of calibration also.
