The OI Analytical Model 1020A Total Organic Carbon Analyzer is an automated system for the selective analysis of total carbon (TC), total organic carbon (TOC), total inorganic carbon (TIC) and volatile organic carbon (VOC) in aqueous samples. The 1020A uses high temperature combustion oxidation combined with non-dispersive infrared detection technology for efficient and selective detection of carbon in a variety of matrices. This combustion instrument is specifically designed to meet USEPA, Standard Methods and ASTM methods for the analysis of water with higher carbon levels such as those found in wastewater and seawater.
