Mettler-Toledo Presents Webinar on Minimizing Out-of-Specification Errors

Published: Apr 23, 2013

COLUMBUS, Ohio (April 23, 2013) – METTLER TOLEDO is pleased to present a complimentary webinar on how to minimize out-of-specification (OOS) errors using a risk-based gravimetric approach.

OOS errors are a major concern within analytical and QA/QC laboratories in the pharmaceutical industry because of the time and resources to investigate the source of the problem. Fifty percent of OOS errors can be attributed to either sample-preparation steps or operator error. Confidence in analytical results begins with accurate weighing because errors in the first step will have a carryover effect. Determining the risk within a process, respecting the minimum weight, and applying the appropriate safety factor during the weighing step can address most of the weighing errors. Error-prone manual steps, undertaken during preparation of a specific concentration of solution, especially those involving volumetric glassware, can easily be replaced by the more accurate gravimetric equivalent. In addition, automation has the potential to eliminate user variability.

This 60-minute webinar will explain how to use an automated gravimetric approach to improve sample-preparation workflows by offering insight from leading industry experts, including Dr. Charles Ray, former Associate Director of Analytical R&D at Bristol-Myers Squibb, who will share his practical experience in managing analytical workflows.
