USP 1058 analytical instrument qualification

USP 1058 analytical instrument qualification is about ensuring that an instrument is suitable for its intended use and application. While system suitability and method validation activities have specific guidelines and procedures; analytical instrument qualification is not so specific. There are conflicting opinions and viewpoints regarding USP 1058 analytical instrument qualification.

Though subjective, analytical instrument qualification is central

Analytical Instrument Qualification (AIQ) stands at the base of the components that go into data quality; the other three components being Analytical Method Validation, System Suitability Tests and Quality Control Check Samples. Why is this so? This is because a sound AIQ lies at the root of the ability of an instrument to meet its intended application. AIQ is not a standalone event in the analytical instrument qualification process. It consists of many related activities.

The four phases of AIQ

USP 1058 analytical instrument qualification requires activities to be grouped into four phases: Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).In brief, these are what these phases are:

Design Qualification

According to USP 1058 analytical instrument qualification; a DQ is the documented set of activities that lay out the functional and operational specifications of the instrument. It also mentions the criteria for selection of the vendor, based on the intended purpose of the instrument. The DQ can be performed by both the manufacturer and the user.

Installation Qualification

IQmay be described as the documented collection of activities that are necessary to establish that an instrument is a) delivered as designed and specified; b) it is properly installed in the selected environment, and c) this is done in an environment that is suitable for the instrument. Whether an instrument is new or was pre-owned, or exists on site but has not been previously qualified; IQ is required.

Operational Qualification

OQ testing follows IQ. It concerns the operational part of AIQ. It is the documented set of activities with which to demonstrate the ability of an instrument to function according to its operational specification in the selected environment.

Performance Qualification

PQ is the last stage of USP 1058 analytical instrument qualification. PQ is the documented collection of activities that is necessary to show that an instrument consistently performs according to the specifications defined by the user, and is appropriate for the intended use.
