Clean equipment is vital to the pharmaceutical industry due to potential cross contamination between product runs of various drugs.

Total Organic Carbon (TOC) analysis is a widely accepted way to analyze for residual pharmaceutical components.

WOT-100 TOC analyzer adopts the UV light-activated persulfate oxidation method. 

TOC content is determined by first removing inorganic carbon (IC) from the sample through the addition of

phosphoric acid. The organic carbon is oxidized to carbon dioxide (CO₂) using UV oxidation with

sodium persulfate. The CO₂ produced is then swept to the non-dispersive infrared detector (NDIR) and

measured. 

Based on above steps, we can get the TC and TIC, thus the TC - TIC= TOC.

UV light-activated persulfate oxidation method.
