Device for measuring TC, TOC, TIC, and TN

摘要

The total carbon and total organic carbon and total inorganic carbon and total nitrogen measurement device starts The. Total carbon and total organic carbon and total inorganic carbon and total nitrogen measurement device according to the invention the oxidation reactor 100, a carrier gas pump 102, sample injection device 104, the first solenoid valve 106, the distribution jig (106A), TOC measurement port (110), TIC measurement port 120, the second solenoid valve 130, the third solenoid valve 132, the fourth solenoid valve 134, the fifth solenoid valve (152), and a sixth solenoid valve 154, and a seventh solenoid valve (170). Total carbon and total organic carbon and total inorganic carbon and total nitrogen measurement device according to the present invention measures the TOC and TIC independently for TC can be obtained by calculation by TC = TOC + TIC. In particular, the TOC of the TOC is measured after removing the TIC component directly. Therefore, the conventional method of measuring the TC and TIC and TOC = TC - higher accuracy than the method to obtain the TOC by calculating the TIC. Further, the device according to the invention as described above is also supplied to give the air filling mubang ceramic balls without using a platinum catalyst, and without using a high purity nitrogen as a carrier gas there is adopted a method for heating to a high temperature by oxidation There are advantages for the measurement because the price is cheap.
