AST-CD-800 Total Organic Carbon Analyzer

Product Introduction
Principle: The sample is fully combusted and decomposed into carbon dioxide and water at high temperature using a high-performance oxidation catalyst in a combustion furnace. Water vapor is removed after cooling by a condenser. Carbon dioxide is measured using a non-dispersive infrared detector (NDIR), thus determining the total organic carbon (TOC) content in the sample. Similarly, inorganic carbon in the sample is decomposed into carbon dioxide and water using an acid reagent. Water vapor is removed after cooling by a condenser, and carbon dioxide is measured using an NDIR, thus determining the total inorganic carbon (TIC) content in the sample. Total organic carbon (TOC) = TC – TIC.

Product Features
