1. Characteristics - High degree of automation:
based onWindowsChinese operation interface, direct human-machine dialogue. The collection, processing, storage, and printing of data are controlled by computers.The instrument automatically adjusts gas flow rate, samples, cleans, changes samples, generates standard curves, and goes into sleep mode after the analysis process is completed. It can also be set to wake up at regular intervals, fully realizing unmanned analysis.

2. The instrument execution standard is：

SH/T 0657-1998 Determination of Trace Nitrogen in Liquid Petroleum Hydrocarbons (Oxidative Combustion and Chemiluminescence Method)
ASTM D4629-2010 Standard Test Method for Trace Organic Compound Nitrogen in Liquid Petroleum Hydrocarbons by Injection/Insertion Oxidized Fuel and Chemiluminescence Method、ASTM D5762-2010 Test Method for Nitrogen in Petroleum and Petroleum Products by Ship Inlet Gas Chemiluminescence Method ASTM D6069-2001- Standard Test Method for Trace Nitrogen in Aviation Hydrocarbons by Oxidative Combustion and Reduction Pressure Chemiluminescence Detection Method;GB/T 17674-1999 Determination of nitrogen content in crude oil and its products - Chemiluminescence method

GCTN-9Type 000fully automaticAdvantages of Luminescence Nitrogen Analyzer

1. The instrument adoptsVertical injectionpattern.
2. Implement injection needleAutomatic cleaning and sample replacement，The program can be set according to requirements.
3. Choose 16bitaboveFully automatic sampler, accurate positioning, one-time setting, fully automatic detectionIt can automatically set the injection volume. Realize unmanned operation and automatic analysis.
4. The gas flow rate is precisely controlled by a mass flow meter，No manual adjustment is required.
5. The gas pressure and temperature are precisely controlled by response sensors.
6. The computer controls the entire process of analysis, data processing, etc., and displays the working status of the entire process. The standard curve can be automatically completed.
7. Using imported high-quality heating furnace wire,delayLong service life of cracking furnace. The data processing software has an over temperature protection automatic cut-off function. When the temperature exceeds the set upper limit, the instrument automatically cools down and enters the protection state.
8. Unique nitrogen reaction chamber enhances the reaction strength between nitric oxide and ozone, as well as rapidly discharges exhaust gas and reduces tailing.
9. The aromatic hydrocarbon barrier filtration system and detection system with selective permeable membrane are impossible to contaminate.
10. Specially designed quartz cracking tube, no need to disassemble or replace, completely solves the problem of carbon deposition in combustion tubes.
11. The instrument is equipped with a gas filtration and purification system.
12. Abnormal gas flow rate and pressure, automatic cooling protection of the instrument.
13. Gas pipelines are connected using spherical clamps for easy maintenance.
14. The instrument can set the temperature and sleep/wake functions of the cracking furnace. After analyzing the sample, the instrument automatically enters sleep mode.
15. The key components are imported componentsReduced instrument noise and improved detection sensitivity.
