SYSTEM FOR UNIFIED ANALYSIS AND MEASUREMENT OF VARIOUS FORMS OF CARBON AND NITROGEN WHICH EMPLOYS CALIBRATION CURVE BASED ON ORGANIC COMPOUNDS

摘要

PROBLEM TO BE SOLVED: To establish a unified analysis method for quantitative determination of TOC, IC, TC, DOC, POC, VOC, NVOC, PM2.5, VON, DON, PON, IN, ON, and TN.;SOLUTION: As it is possible to combust organic form carbon and nitrogen between 450°C and 650°C by using effect of a catalyst filled in a combustion tube, in a first oven, a sample of organic form carbon and nitrogen is decomposed according to material properties of the sample such as boiling point or decomposition point, and in a second oven, the sample is combusted, then finally, the sample is combusted in the first oven at a high temperature to determine fractional quantities. This method can be applied to creation of a calibration curve based on accurately refined organic compounds of which composition ratio is identified, so that it is possible to maintain compatibility in measurement values which is acquired by different domestic and overseas institutions and can be easily verified. Thus, the method has clear traceability and serves as practical measurement standards.;COPYRIGHT: (C)2014,JPO&INPIT
