The HTTN-6000 chemiluminescence nitrogen analyzer system uses the chemiluminescence method to determine the total nitrogen content, which improves the ability to resist impurity interference, avoids the cumbersome operation of the titration cell in the coulometric method and the resulting unstable factors, and thus greatly improves the sensitivity of the instrument. The key components of the system adopt imported devices, which ensures the reliable performance of the whole machine. Application fields: environmental protection, chemical industry, biological industry, petroleum, energy.

Main Features：

High sensitivity – The HTTN-6000 system uses a chemiluminescence method to determine total nitrogen content, which enhances its ability to resist interference from impurities. It avoids the cumbersome operation of the titration cell associated with the电量法 (electric quantity method) and the resulting instability factors, thereby significantly improving the sensitivity of the instrument. The key components of the system adopt imported devices, ensuring reliable performance of the entire machine.
