Follow on Google News | METTLER TOLEDOs Weighing Standard Ensures USP Compliance Free new interactive On demand WebinarUnited States Pharmacopeia (USP) published the revised mandatory Chapter 41 on balances as well as new updates to the advisory Chapter 1251.
For a long time balance users and manufacturers argued that balance assessment as per USP's General Chapter 41 ("Balances") was unclear and difficult to comply with. In addition, they frequently commented that General Chapter 1251 ("Weighing on an Analytical Balance") no longer represented state-of-the- Demanding Balance Assessment The new requirements of General Chapter 41 are mandatory. The revised chapter details a relatively demanding balance assessment, outlining accuracy and repeatability tests for calibrated balances used to weigh analytes for quantitative measures. Since accuracy can only be gauged using weights that are at least 5% of an instrument's capacity, test weight selection criteria have also been modified accordingly (weights smaller than 5% cannot assess systematic deviations sufficiently well enough). Achieve Time Savings without Compromising Accuracy General Chapter 1251 provides additional clarification on the new procedures and extends the scope to any balance used for an analytical procedure. It details that balance performance verification should be carried out using a risk-based approach. Very importantly, it is recommended to only weigh net samples which weigh sufficiently more than the minimum weight to account for fluctuations in the balance's performance due to varying influences from the environment and the balance operators. This requirement is clearly applied to the sample weight itself-and not to the tare vessel. Additionally- Ensuring Accuracy in the New Environment Although these revisions imply that unnecessary testing must be eliminated to protect manufacturing margins in today's highly competitive pharmaceutical market, they continue to underscore that weighing accuracy is non-negotiable. METTLER TOLEDO's GWP - The Weighing Standard-can help manufacturers implement the new USP regulations. Tailored to each weighing application, GWP Verification is a unique, risk-based service that helps eliminate redundant or erroneous testing. Thanks to determining the minimum weight and measurement uncertainty for each and every balance and scale used in the weighing process, manufacturers not only optimize SOPs, ensure consistent product quality and pass air-tight audits, they also avoid potentially costly litigation and fines resulting from a poorly-formulated, out-of-specification product. Consistent Quality with GWP Verification With daily testing out of the way, pharmaceutical manufacturers have the opportunity to strengthen their balance testing procedures and create enhanced assurance that their products remain safe, effective, and profitable. GWP Verification's unique, systematic guidance can help make weighing consistency- METTLER TOLEDO's free On-Demand Webinar explaining the implications of the new USP revisions can be viewed at: http://us.mt.com/ About Mettler Toledo: METTLER TOLEDO specializes in the area of precision instruments for professional use.
