TESTA Analytical Solutions:
Liquid Chromatography Flowmeter
HPLC Pumps are commonly calibrated with a gravimetric method by weighing the amount of solvent delivered within a given time and then, using density as parameter, calculating the real flow rate. While this method can be extremely accurate, it is also relatively time consuming, often taking in excess of 30 minutes. The TESTA Liquid Chromatography Flowmeter can measure HPLC flow rate in real time and it also tracks each measurement automatically with microsecond resolution, thus allowing fast and reliable collection of flow rate data. It can be demonstrated, using the flowmeter that you can achieve calibration of a typical HPLC pump in less than 3 minutes with an accuracy comparable or even superior to the gravimetric method.
