Total Organic Carbon Analyzer

Description

TOC-A2000 and TOC-A5000P total organic carbon analyzer is a highly automated laboratory water quality analyzer. May use it to analyze high salt sample types and has automatic dilution, purging, and acid addition capabilities. The biggest advantage of this total organic carbon analyzer is the thorough oxidation and digestion, which can oxidize not only low molecular weight organic compounds that are easy to decompose but also insoluble macromolecular organic compounds that are difficult to decompose.

How does a toc analyzer work
A TOC (Total Organic Carbon) analyzer works by measuring the total amount of organic carbon in a sample. The process involves three main steps:
Sample Preparation: The sample is usually acidified to remove inorganic carbon (such as carbonates) by converting it into carbon dioxide (CO2), leaving only the organic carbon.
Oxidation: The remaining organic compounds in the sample are oxidized, often by high-temperature combustion or chemical oxidation, to convert them into CO2.
Detection: The CO2 produced during oxidation is measured using either infrared detection or a conductivity meter. The amount of CO2 is directly proportional to the organic carbon content in the sample.
This method provides an accurate measure of total organic carbon, important for monitoring water quality, environmental testing, and industrial processes.
