[Application Note] Detection of Sodium Hydroxide Using TOC and Conductivity
Sodium hydroxide is a commonly used cleaning agent in the pharmaceutical industry. However, it cannot be detected by TOC because it does not contain carbon. Therefore, using conductivity for detection is effective. However, there are often trace amounts of residual organic matter, and TOC measurement is essential for detecting this. The Sievers M9 TOC analyzer can simultaneously measure both conductivity and TOC, making it useful for detecting residual concentrations of sodium hydroxide.
