TOC (Total Organic Carbon) analysis is a laboratory technique used to measure the amount of organic carbon present in a sample. The equipment needed to perform TOC analysis includes:
TOC Analyzer: This is the primary instrument used for measuring organic carbon in a sample. There are various types of TOC analyzers available, including high-temperature combustion, UV-Persulfate oxidation, and wet chemical oxidation.
Autosampler: This device is used to automate the sample introduction process, allowing for the analysis of multiple samples in a single run.
Sample Vials: These are containers used to hold the sample during analysis.
Purge Gas: TOC analysis requires the use of a purging gas, such as nitrogen or helium, to remove any carbon dioxide that may be present in the sample.
Deionized Water: This is used for diluting the sample before analysis and for rinsing the equipment.
Calibration Standards: These are used to calibrate the TOC analyzer to ensure accurate measurements.
Combustion Tube: This is a glass tube used in high-temperature combustion TOC analyzers to burn the sample and produce carbon dioxide for analysis.
Catalyst: In high-temperature combustion TOC analyzers, a catalyst is used to speed up the combustion process.
Carrier Gas: This is used to transport the combustion products from the combustion tube to the detector.
Detector: This is used to measure the amount of carbon dioxide produced during the combustion process and determine the amount of organic carbon present in the sample.
Computer System: A computer is used to control the TOC analyzer and collect, process, and store data.
Overall, TOC analysis is a complex and sensitive laboratory technique that requires specialized equipment and skilled personnel to ensure accurate and reliable results.
