Contact formThe HTTN-3000 Luminescent Nitrogen Analyzer system uses the chemiluminescence method to determine the total nitrogen content, which enhances 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.
Main Features：
1. High sensitivity: The HTTN-3000 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电量法 (coulometric method) and the resulting unstable factors, and greatly enhances the sensitivity of the instrument. The key components of the system adopt imported devices, which ensures the reliable performance of the whole machine.。
2. The implementation standard of the instrument is：
| GB/T 17674－2012 | Determination of Nitrogen Content in Crude Oil and Its Products – Chemiluminescence Method |
| SH/T 0657－2007 | Method for Determination of Trace Nitrogen in Liquid Petroleum Hydrocarbons (Oxidative Combustion and Chemiluminescence Method) |
| SH/T 0704－2001 | Test Method for Nitrogen Content in Petroleum and Petroleum Products (Boat Injection Chemiluminescence Method) Petrochemical Industry Standard |
| ASTM D4629－2017 | Standard Test Method for Determination of Trace Organically Bound Nitrogen in Liquid Petroleum Hydrocarbons by Injection/Insertion of Oxidative Fuel and Chemiluminescence |
