BRIEFING

 〈731〉 Loss on Drying. This proposal is based on the version of the chapter official as of November 1, 2020. Based on frequently asked questions from users, it is proposed to incorporate the numerical definition of vacuum from General Notices, 8.210 Vacuum and to add the term “absolute” to the expression “pressure of less than 20 mmHg (2.67 kPa)”. This clarification is intended to explicitly define the pressure reference and ensure consistent interpretation of the vacuum specification.

 Additionally, minor editorial changes have been made to update the chapter to current USP style.
