Sample Collection Procedures for Quality Testing in MDIs

1) Purpose

The purpose of this SOP is to establish procedures for the collection of samples during the manufacturing of metered-dose inhalers (MDIs) for subsequent quality testing to ensure product quality and compliance with specifications.

2) Scope

This SOP applies to all personnel involved in sample collection activities within the MDI production facility, including production operators, quality control technicians, and validation specialists.

3) Responsibilities

The responsibilities for this SOP include collecting representative samples, ensuring sample integrity, labeling samples, and documenting sample collection activities. Specific roles include:
Production Operators: Collect samples at designated stages of the manufacturing process.
Quality Control Technicians: Receive and log samples for testing in accordance with sampling plans.
Validation Specialists: Monitor sample collection procedures and ensure compliance with protocols.

4) Procedure

4.1 Sampling Planning
4.1.1 Define sampling points and frequencies based on production batch size and critical process parameters.
4.1.2 Develop sampling plans to ensure representative samples are collected throughout the production process.
4.2 Sample Collection
