Even though automated testing equipment greatly improves testing efficiency and flexibility, it also presents the risk of overlooked testing bias.
With instrument performance left unchecked, measurement bias can falsely present product as meeting specification when, in truth, it fails established quality standards. Such a situation not only places customers safety at risk, but also jeopardizes your own company’s reputation. By routinely verifying your instrument’s performance, you’ll ensure consistent quality that meets expected performance demands.
Depending upon your weekly sample load and your instrument’s test characteristics (i.e. test duration, sample volume, system stability, etc.), some tests may easily and cost-effectively benefit from higher frequency verification while others require checking less often. Your best line of defense against test bias is a consistent verification program. We suggest implementing this step within a standard quality control procedure. Exporting reference data to a LIMS will further enable statistical process control (SPC) — a powerful tool for measuring laboratory performance.
