Total Organic Carbon Analysis for Cleaning Validation in Pharmaceutical Manufact

Karen A. Clark, Product Manager, Anatel Corporation
ISPE, October 2000 In the pharmaceutical industry, Good Manufacturing Practices (GMPs) require that the cleaning of drug manufacturing equipment be validated.1 Many different validation techniques can demonstrate that the manufacturing equipment is cleaned and essentially free from residual active drug substances and all cleaning agents.Common analytical techniques in the validation process include HPLC, spectrophotometry (UV/Vis), and TOC. HPLC and UV/Vis are classified as specific methods that identify and measure appropriate active and substances. TOC is classified as a non-specific method and is ideal for detecting all carbon-containing compounds including active species, excipients, and cleaning agent(s). 2,3,4,5.
