Abstract: Dissolved organic carbon (DOC) is an important component of water and plays an essential role in the biogeochemical reactions of water as an electron donor in biological metabolic processes. Conventional mass spectrometry instruments have high requirements for the pre-treatment of water samples, and spectroscopy instruments have low precision and poor stability when testing DOC below 7 ppm, which do not satisfy the testing needs of low concentration samples such as drinking water, surface rivers, underground rivers, reservoirs and lake water samples. In this presentation, we will introduce an isotope testing method for low concentration of organic carbon in water by using the instrument of Total Organic Carbon analyzer and Laser Spectroscopic Isotope meter (LSI) , and answer FAQs.
