Verify testing Equipment Accuracy and Precision Certified Reference Materials CRM Why use reference materials? Though automated testing equipment greatly improves testing efficiency and flexibility, it also presents a risk: overlooked testing bias. With instrument performance left unchecked, measurement bias can gradually eat away at your profitability. Or worse, it can falsely present product as meeting specification when, in truth, it fails established quality standards. Such a situation not only places customer safety at risk, but also jeopardizes Depending upon your weekly sample load your own company’s reputation. and your instrument’s test characteristics By routinely verifying your (i.e. test duration, sample volume, instrument’s performance, you’ll ensure system stability, etc.), some tests may consistent quality that meets expected easily and cost-effectively benefit from performance demands. higher frequency verification while PAC CRM Know that requirements of all quality systems are met HOw OFtEN SHOuLd yOu vERIFy tEStINg others require checking less often. Your Establish good inter-laboratory correlation Generate reliable test data from automatic, semi-automatic, and manual equipment best line of defense against test bias is a consistent verification program. We suggest 1. What test method are implementing this step within astandard quality control procedure. Exporting reference data to a LIMS will further enable instrument used? statistical process control (SPC) — a powerful tool for measuring laboratory verification protocol?
