An article on weighing according to the European Pharmacopoeia has been published in Pharmeuropa Bio & Scientific Notes and is referenced in Medline/PubMed®.
Weighing is a key activity in every quality control laboratory as it is one of the first steps in the preparation of samples and reagents for most analytical procedures. It is also critical because weighing errors add up and propagate throughout the entire analysis process, affecting the accuracy and precision of reported results. A new general chapter, Balances for analytical purposes (2.1.7), was adopted at the 168th session of the European Pharmacopoeia (Ph. Eur.) Commission in November 2020 and included in Ph. Eur. Supplement 10.6, which became applicable on 1 January 2022. It sets out clear requirements for an instrument that is essential to every analytical procedure described within the pages of the Ph. Eur.
The article “Weighing according to the European Pharmacopoeia: general considerations and new general chapter 2.1.7. Balances for analytical purposes” explains in detail requirements specifically related to this topic in Ph. Eur. texts and generally reviews the other quantity-related requirements.
