Calibration of Instruments

Instrument calibration is one of the primary processes used to maintain the instrument accuracy.  Calibration  is process of configuring an instrument to provide a result for a sample within an acceptable range. Eliminating factors that cause inaccurate measurements is a fundamental aspect of instrumentation design. Although the exact procedure vary from product to product, the calibration process generally involves using the instrument to test samples of one or more known values called as “calibrators.” The results are used to establish a relationship between the measurement technique used by the instrument and the known values. The process in essence teaches the instrument to produce results that are more accurate than those that would occur otherwise. The instrument can then provide more accurate results when samples of unknown values are tested in the normal usage of the product. Calibrations are performed using only few calibrators to establish the correlation at some spe...
