Flow Accuracy verification
Posted: Fri Jan 10, 2014 5:11 pm
Hi all we qualify our HPLC flow rate as below and to the ranges specified. Why does the specification range vary for each flow rates tested? Is it to do with the pumps accuracy/capablities at different flows?
Set flow = 0.5 acceptable limit = 0.469 - 0.531 (about +- 6%)
Set flow = 1.0 acceptable limit = 0.968- 1.032 (about +- 3%)
Set flow = 5.0 acceptable limit = 4.95 - 5.06 (about +- 1%)
Thanks in advance
