TOC analysis

In the pharmaceutical industry, the TOC (total organic carbon) value is considered an important bulk parameter for evaluating the organic contamination of a water sample. That is why the TOC value is also very suitable for cleaning validation. We use two methods for this analysis: NDIR detection and the wet chemical UV persulfate method. The following can be named as characteristic features: high sensitivity; detection limit of 100 ppb; fast and reliable; not suitable for waste water and samples containing particles and a high salt load; corresponds with USP and Ph.Eur.
