The amount of solvents used will be calculated correctly only under<br />

software control. Should the pumps have been controlled manually,<br />

Qualification Procedures<br />

ChromGate ® provides a performance qualification tool for checking your<br />

HPLC systems. This is not a qualification procedure for each individual<br />

device (pump, detector etc.) but for the whole configured chromatographic<br />

instrument. The procedure is at last a normal method used to<br />

determine the measurement reproducibility.<br />

The PQ procedure is started from the main instrument screen by<br />

selecting the menu sequence<br />
