What are some Qualification Criteria of IQ/OQ v. PQ?



OQs test the fitness of an HPLC instrument against the intended Instrument design specifications.
These test the instrument components of an HPLC.


A typical OQ would include having an in-house or contract organization perform instrument repairs/preventative maintenance on your instrument and then test them to qualify them to the instrument design specs. Example of these tests would be:
Autosampler volume accuracy (weighing)
Pump leak-down tests
