Before explaining how HPLC liquid flow meters work here’s an explanation of what digital HPLC flow meters do: Digital HPLC flowmeters are used to measure the accuracy of High Performance Liquid Chromatography pumping systems in order to meet FDA and other regulations regarding 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.
The process demands accurate, reproducible column retention time as an analyte (what is being analyzed) is pumped through the HPLC system.
These precision instruments are not to be likened to flow meters used on process lines measuring flow rates in, for example, thousands of gallons per minute but instead in fractions of milliliters per minute.
Why HPLC Pump System Accuracy is Important
As suggested above, meeting regulations (and protecting a company’s reputation) is the reason. Consistent accurate performance is an absolute necessity. … Read the rest
