Liquid Borne Particle Count (LBPC) – Principle, Procedure, Calculation, and Acceptance Criteria
Liquid Borne Particle Count (LBPC): Principle, Procedure, Calculation & Acceptance Criteria Explained Liquid Borne Particle Count (LBPC) is a critical quality control test used in pharmaceutical manufacturing to measure particulate contamination in liquids such as Water for Injection (WFI) , Purified Water , injectable solutions, ophthalmic preparations, and parenteral products. Unlike visual inspection, LBPC provides a quantitative, size-based assessment of particles that can compromise patient safety and product quality.
