Our lab just acquired a 1200 stack with a BIN SL pump. Now, we have an unusual high pressure, with open valve, it fluctuates between 10-15 bar. With close valve, at 2ml/min, it shoots up to 400 bar.
I attempted to change the pump head A with another one that is working great, and yet the problem persists.
Also, we are using Chemstation B.04.03 SP2 and under pump control, only H2O is listed, and a message displays "the seperate Agilent LC Diagnostic Software provides ability to calibrate pump for individual solvent". We are using the regular solvents, Isopropanol, methanol, acetonitrile etc...
Any tips or guidelines would be very appreciated.
Thank you all,
