Certificate USP General Chapter 41 - Mettler Toledo
USP General Chapter 41 states: 'Because the standard deviation is virtually independent of sample mass within the balance's capacity, use of a small test load, which may be difficult to handle, is not required' In cases where the test load is different than the smallest net weight, the assessment of the
1225 validation of compendial methods Test procedures for assessment of the quality levels of pharmaceutical products are subject to various requirements According to Section 501 of the Federal Food, Drug, and Cosmetic Act, assays and specifications in monographs of the United States Pharmacopeia and the National Formulary constitute legal standards
The guidelines in the present discussion are contained in Chapter 621 (abbreviated by the United States Pharmacopeia [USP] and here as <621>) of the USP (1) The USP is updated at least twice a year, so it is wise to check the most recent edition for any chang
