Standard Chromatographic Tests
In this section are standard chromatographic tests for carry-over and
repeatability described. These tests should provide basic information for
support and user.
The described tests are examples only and should be varied accordingly if the
configuration of the HPLC system changes.
The test is laid out for standard valves with a bore size of 0.25 mm which
allows a flow rate range of 10 to 500 µL/min.
For both tests, carry-over and repeatability, will test conditions be described
for UV and LC/MS detection.
Details are listed below. It has to be emphasized that the given levels to reach
for carry-over and repeatability do not reflect the specification value. These
described tests should give the operator a confirmation if the system is
working within expectation with a reasonable effort and time frame. The tests
are more comparable with an OQ Test (Operational Qualification Test).
