Total Organic Carbon (TOC) plays a vital role in today’s laboratory. There are two main types of TOC systems in today’s market: UV-Persulfate oxidation, and high temperature combustion oxidation. While these two systems have some areas of overlap, they offer different solutions for the laboratory. 

Read more to learn about the differences between these two systems.

Total organic carbon (TOC) analyzers play a significant role in our pharmaceutical testing laboratories and manufacturing facilities. Water is a major excipient and solvent used in pharmaceutical manufacturing and cleaning processes. It must be tested regularly for TOC. TOC analyzers are used globally to measure the amount of organic carbon that is present in water and in the equipment for cleaning validation. TOC is also used to test water sources for injection and has other uses within the pharmaceutical landscape.

Pharmaceutical production entails strict quality control and precise analytical testing methods. The United States Pharmacopeia (USP), European Pharmacopeia (EP) and Japanese Pharmacopeia (JP) have promoted TOC analysis as the analytical technique to verify that cleaning validation, purified water (PW) and water for intravenous injection (WFI) meet the high standards of the pharmaceutical industry.

Total Organic Carbon (TOC) is defined as the amount of carbon bound in an organic compound and is often used as a non-specific indicator of water quality or cleanliness of pharmaceutical manufacturing equipment.
