operational qualification


The LC Services Ltd Operational Qualification (OQ) Procedures have been designed in line with good laboratory practice (GLP) and good manufacturing practices (GMP), which require that all laboratory instrumentation shall be adequately inspected, cleaned and maintained. Instruments used for generation, measurement and evaluation of data shall be adequately tested, calibrated or standardised. LC Services Ltd protocol (available on request) will define the methods and documentation that will be used to evaluate the HPLC instrument or system for operation in accordance with the intended use. Successful completion of this protocol will verify that the HPLC instrument or system is operation to your acceptance limits


The OQ procedures use a combination of test functions and analytical methods (using certified samples & equipment) to evaluate and verify the instrument or system is operation according to acceptable limits.


All preventative maintenance / repairs must be completed and instrument tests carried out prior to a qualification procedure being undertaken. In the event of any problems, consultation with an LC Services Ltd Service Manager or Senior Engineer must be initiated. All standards and equipment used for qualification must be checked for compliance prior to qualification. Any certification for equipment / standards used are available upon request.


Once all equipment has undergone initial maintenance / repair, operational qualification can be carried out in accordance with this protocol. All raw data collected is obtained using calibrated standards / equipment, which is traceable to nationally recognised standards. All chromatographic data is captured on the customer’s system and folders are generated to store the data. The OQ is performed on our very own tailor made software, generates certificates on site and is electronically signed by the engineers’ personal login.


All criteria can be tailored to the customers individual specification and the final certification is backed up to the LC Services Ltd server.
