Study on the calibration method of chemiluminescence nitrogen analyser

The measurement characteristics of chemiluminescence nitrogen analyser directly affect the measurement results of total nitrogen content. In order to promote the development of petroleum technology, the corresponding calibration method is studied to ensure the accuracy and reliability of the quantity value. On the basis of fully understanding the structure and working principle of the chemiluminescence nitrogen analyzer, the main measurement parameters were analyzed, and the calibration feasibility was analyzed combined with the corresponding standards and measurement technical specifications. The specific calibration method was determined, which was verified by experiments to provide technical basis for the effective traceability of the chemiluminescence nitrogen analyzer.
