General chapters USP 41 and Ph. Eur. 2.1.7 address equipment performance and introduce three measures that must be carried out periodically to optimize the performance of analytical balances:
- Calibration documented in a calibration certificate (incl. measurement uncertainty)
- Performance checks (routine testing) between calibration intervals
- Adjustment by built-in weights
Our Good Weighing Practice Program (GWP®)supports the balance chapters of these Pharmacopoeias, providing a clear and detailed plan of how to specify, test and calibrate balances.
