TOC Analyzers

A typical analysis for TOC measures both the total carbon present as well as the so called "inorganic carbon" (IC), the latter representing the content of dissolved carbon dioxide and carbonic acid salts. Subtracting the inorganic carbon from the total carbon yields TOC. Another common variant of TOC analysis involves removing the IC portion first and then measuring the leftover carbon. This method involves purging an acidified sample with carbon-free air or nitrogen prior to measurement, and so is more accurately called non-purgeable organic carbon (NPOC).

Our range of TOC Series utilizes the 680 °C combustion catalytic oxidation method to efficiently analyze all organic compounds. With a wide sample range from 4 μg/L to 30,000 mg/L, the TOC is suitable for analyzing ultra-pure to highly contaminated samples of wastewater, brine water, seawater, drinking water and pharmaceutical water. 

The TOC Series offers a number of features, including automatic sample acidification and sparging, an automatic dilution function, and a zero-maintenance Peltier cooler, for easier, more accurate analysis. A number of options, including salt kits, autosamplers, and a total nitrogen module, improve productivity.
