Provisions
Every instrument used for a release determination is on a calibration schedule with a named interval
Calibration is against traceable reference standards, and the certificate is retained
Analytical balances, pH meters and HPLC systems are checked with system suitability before each analytical run
An instrument outside calibration invalidates results generated since its last passing check, and those batches are re-analysed
Calibration records are retained for the life of the instrument plus the retention period
