Instrument & System Suitability Specification

This specification defines the Quality Unit–approved requirements for determining the suitability and readiness of instruments and analytical systems used to generate GMP-relevant test results.

Specification Type:
Authoritative Quality Control specification defining instrument and system suitability requirements and decision authority. This document does not define equipment operation, calibration procedures, or maintenance instructions.

1. Purpose

To establish Quality Unit–approved criteria for verifying that instruments and analytical systems are suitable for use at the time data is generated, ensuring the reliability and validity of GMP-relevant analytical results.

2. Scope

This specification applies to all instruments, equipment, and analytical systems used to support GMP testing, measurement, or evaluation activities, including laboratory instruments, computerized systems, and associated measurement devices.

Applicable Business Domains include:

3. Ownership & Governance

Instrument and system suitability requirements defined in this specification shall not be modified outside approved QMS change control.

4. Instrument & System Suitability Requirements

Suitability Attribute Requirement Applicability
Qualification Status Instruments and systems shall be qualified, as applicable, and approved for GMP use prior to generating reportable results. All GMP-relevant instruments and systems
Calibration & Verification Instruments shall be calibrated or verified within defined intervals appropriate to their intended use. Measurement and test equipment
Operational Readiness Instruments and systems shall be in proper working condition and free from known defects at the time of use. All analytical systems
System Suitability Checks Where applicable, system suitability checks shall demonstrate acceptable performance prior to or during analytical use. Methods requiring system suitability evaluation
Change & Incident Impact Equipment changes, failures, or incidents shall be evaluated for impact on data reliability and suitability. Instruments affected by changes or events

Demonstration of instrument and system suitability may include qualification, calibration, verification, system suitability testing, or other approved mechanisms appropriate to the system and intended use.
