I am seeing an incorrect flow rate between 1 and 50 ml/min., with no column (or back pressure), what should I do?
Concerned instruments: puriFlash 215, puriFlash 430, puriFlash 450, puriFlash 4100, puriFlash 4250
Concerned module: pump
Flow rate tests are conducted as per our "Operational Qualification", with back pressure.
Check the flow rate with back pressure (column or micrometric valve).
And reproduce the "Operational Qualification".
