GCTN-9Type 000fully automaticAdvantages of Luminescence Nitrogen Analyzer

1. The instrument adoptsVertical injectionmode.

2. Implement injection needleAutomatic cleaning and sample replacement，The program can be set according to requirements.

3. select16positionthe aboveFully 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,extendLong service life of cracking furnace. The data processing software has an over temperature protection and automatic cut-off function. When the temperature exceeds the set limitlimitThe instrument automatically cools down and enters a protective state.

8. *The nitrogen reaction chamber enhances the reaction intensity 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.

    The key components are imported componentsReduced instrument noise and improved detection sensitivity.
