The 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
ASTM D5762－2012	Test Method for Determination of Nitrogen in Petroleum and Petroleum Products by Ship Inlet Chemiluminescence Method
ASTM D6069－2001	Standard Test Method for Determination of Trace Nitrogen in Aviation Hydrocarbons by Oxidative Combustion and Reductive Pressure Chemiluminescence Detection

3、System Configuration：
Standard configuration: computer +HTTN-3000 system + liquid sampler
Other optional accessories: solid sampler, gas sampler

4、Easy to operate：
Based on the Chinese operation interface of Windows (7, XP, Me, 98), the operation is more convenient and faster. You only need to click the mouse to complete all parameter settings and condition selection, and the computer will control data collection, processing, storage and printing.
