USP Chapter 1251 is titled ‘weighing on an analytical balance’ and unlike chapter 41 is only a recommendation. The scope of this procedure includes any balances used during an analytical procedure.
The chapter covers the performance of the balance taking into consideration its intended use and the balance location and therefore the environmental effects.
Northern Balances can offer a UKAS Calibration Certificate for your balance to demonstrate how your balance is performing, and can also offer ‘IQ OQ PQ’ (Installation Qualification, Operational Qualification and Performance Qualification) to establish that the type of equipment is correct for use and performing as it should. If you require further guidance on which service is most suitable for you, please speak to our metrology experts.
