Inline pH Control System – Equipment Validation SOP

Standard Operating Procedure for Validating Inline pH Control System

Purpose

The purpose of this SOP is to establish the requirements for validating the Inline pH Control System used in the production of IV Infusions to ensure compliance with regulatory standards and maintain product quality.

Scope

This SOP applies to the Inline pH Control System utilized in the adjustment of pH during the compounding process of IV Infusions in the production area.

Definitions

  • IV Infusions: Intravenous solutions delivered through bags or bottles.
  • Inline pH Control System: A system designed to monitor and adjust pH levels during compounding.
  • Criticality: Indicates the impact of the equipment on product quality.

Roles

  • Validation Team: Responsible for executing validation protocols.
  • Quality Assurance: Oversees compliance with SOPs and regulatory requirements.
  • Production Personnel: Operate the Inline pH Control System during compounding.

Lifecycle Procedure

  1. Design Qualification (DQ): Assess user requirements and system design.
  2. Installation Qualification (IQ): Verify installation against specifications.
  3. Operational Qualification (OQ): Confirm system operates within defined parameters.
  4. Performance Qualification (PQ): Validate system performance during actual use.

Good Documentation Practices (GDP) Controls

All documentation must be completed in real-time, signed, and dated by authorized personnel. Records should be maintained in an easily retrievable format.

Acceptance Criteria Governance (URS Annex 11)

Acceptance criteria must be defined in the User Requirements Specification (URS) and shall include parameters for pH range, system accuracy, and response time.

Calibration and Preventive Maintenance (PM) Governance

The Inline pH Control System must undergo calibration annually, with records maintained to ensure compliance. Preventive maintenance should be performed according to the manufacturer’s recommendations.

Change Control Triggers

Any modifications to the Inline pH Control System, including software updates or hardware changes, must initiate a change control process to assess impacts on validation status.

Revalidation Triggers and Periodic Review

Revalidation is required every 12 months or when significant changes occur in the process or equipment. A periodic review of the validation status should be conducted annually.
