High-performance liquid chromatography (HPLC) digital flowmeters are used to measure the accuracy of HPLC pumping systems in order to meet FDA and other regulations regarding the installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) of equipment used in the pharmaceutical and biopharmaceutical industries, as well as other analytical labs.

This month's cover story, "Problem solving with real-time flow measurement," was contributed by TESTA Analytical Solutions. TESTA Analytical Solutions e.K. describes how a leading European manufacturer of chromatography instrumentation is using its liquid chromatography flowmeter to improve the performance of their high-performance HPLC systems.

Flow rate is an important parameter in HPLC systems because it determines retention time or volume and thus has a significant impact on reproducibility. The TESTA Analytical Liquid Chromatography Flowmeter has redefined non-invasive real-time flow rate measurement in HPLC, GPC/SEC, and Ion Chromatography systems.
