Total organic carnon and total nitrogen measuring device based on heat combustion without catalyst

摘要

PURPOSE: A total organic carbon and total nitrogen content measuring apparatus based on a non-catalyst heat combustion oxidation method is provided to successively and accurately measure the total nitrogen in a sample including seawater by enabling complete combustion of a catalyst by promoting the oxidation of the nitrogen. CONSTITUTION: A total organic carbon and total nitrogen content measuring apparatus based on a non-catalyst heat combustion oxidation method comprises a circulating cleansing unit(10), a sample injecting unit(11), a non-catalyst heat combustion oxidation unit(12), a cooling unit(13), a discharging device(14), a filtering device(101), and a detector(15). The circulating cleansing unit performs circulate-cleanses the sample injecting line. The filtering device removes contaminants of carrier gas(100). The detector detects oxidized nitrogen oxides and total organic carbon.
