Product Introduction

The HH-9000SN Fully Automatic Sulfur and Nitrogen Integrated Analyzer is a new generation of fully automatic precision laboratory testing equipment developed based on the dual detection principles of chemiluminescence and ultraviolet fluorescence, combined with modern computer intelligent control technology.

It can efficiently and accurately determine sulfur and nitrogen elements in various samples, and is widely used in petroleum, petrochemical, chemical, environmental protection, and third-party testing fields.

It is adaptable to the testing needs of various sample types, including liquids and gases, providing an efficient, stable, and accurate solution for laboratory testing.

This equipment adopts a vertical sample introduction design, coupled with a rotary automatic sample introduction system, which effectively avoids human error caused by manual sampling, significantly reduces system detection errors, and improves the stability of test results.

During sample testing, users can add new samples at any time according to experimental needs, flexibly expanding the number of sampler positions to meet the needs of multi-batch and diverse testing scenarios.

The gas path control system uses a high-precision mass flow meter, and intelligently regulates the gas flow throughout the process via computer, ensuring stable and fluctuation-free gas flow, further optimizing instrument repeatability, significantly improving the measurement accuracy of low-content samples, and ensuring the reliability of test data.

Basic Parameters

Performance Characteristics

1. High-efficiency pyrolysis design: Utilizing a blind-sleeved quartz pyrolysis tube, the reciprocating combustion technology ensures complete combustion and conversion of the sample. Complete sample pyrolysis can be achieved without the need for a tungsten trioxide catalyst, effectively avoiding carbon buildup, extending equipment lifespan, and reducing maintenance costs.

2. Stable Gas Path System: A dedicated pressure stabilizing device is added to the gas path to effectively suppress interference from gas flow and pressure fluctuations on the detection results, ensuring the stability of the gas path operation and further improving the repeatability and accuracy of the detection data.

3. Flow Control: Equipped with an electronic mass flow meter, the gas flow is controlled in a closed-loop manner by a computer, ensuring stable and fluctuation-free gas flow, significantly optimizing instrument repeatability and improving the measurement accuracy of low-content samples. Simultaneously, when the mass flow meter detects abnormal carrier gas or combustion gas flow, the workstation will automatically pause sample injection to prevent carbon buildup due to sample hypoxia-induced pyrolysis, avoiding contamination of the gas path and detector, and ensuring normal equipment operation.

4. Intelligent Temperature Control: The pyrolysis furnace is equipped with an automatic fan control device. The cooling fan can automatically start and stop according to the furnace temperature, eliminating the need for personnel to wait for shutdown. It features operational fault warnings and a fault-prohibition sample injection function, and also incorporates an automatic over-temperature power-off protection mechanism, comprehensively ensuring the safety of equipment operation and operator safety.

5. High-Sensitivity Detection Chamber: Professional spraying process ensures excellent airtightness of all components in the detection chamber, effectively preventing air and light leaks, reducing external environmental interference, lowering background noise, and further improving instrument sensitivity and detection limits to meet the high-precision detection requirements of low-content samples.

6. High-Quality Core Components: Key components such as UV lamps, monochromators, membrane dryers, and photomultiplier tubes are all high-quality products, ensuring stable and reliable overall equipment performance, extending equipment lifespan, and guaranteeing the accuracy and consistency of test results.

7. Intelligent Workstation System: Integrating single-point and multi-point calibration modes, it can automatically generate calibration curves; it provides multi-point high-order curve fitting function, effectively reducing deviations in low-content sample test results caused by the linear correlation of the fitted curve. The workstation monitors the instrument's operating status in real time, including key parameters such as gas flow rate, pyrolysis furnace temperature, gas pressure, PMT high pressure, and baseline. In case of any abnormality, the instrument will automatically alarm and cool down to enter a protection state, ensuring laboratory operational safety. The entire analysis and data processing process is computer-controlled, offering convenient operation. Equipped with a comprehensive data processing system, it automatically performs functions such as concentration, content, unit conversion, and RSD calculation, improving detection efficiency.

8. Energy-saving and environmentally friendly design: Built-in sleep/wake-up mode allows for freely setting sleep and wake-up delay parameters. During sleep, the furnace temperature automatically decreases, gas flow is reduced or shut off, effectively saving energy and extending equipment lifespan. The delayed wake-up function allows the equipment to preheat to operating temperature for the next detection cycle, improving detection efficiency.

9. Fully automated sample introduction system: Equipped with a 19-bit or 156-bit fully automated sample introduction system, controlled entirely by computer, enabling direct sample introduction and fully automated experimental operation. It automatically completes operations such as sample replacement, injector cleaning, volume difference method bubble error elimination, and automatic standard curve plotting. The injection speed is constant and can be flexibly adjusted according to sample characteristics to adapt to the detection needs of different sample types.

10. Convenient Operation Design: Injector parameters can be set directly on the computer, eliminating the need for individual user adjustments. After starting testing, the device can operate unattended, significantly reducing operator workload, mitigating system detection errors caused by human error in sample introduction, and improving both efficiency and accuracy.

11. Flexible Testing Control: During testing, users can modify key parameters such as the number of tests, injection volume, and analysis time at any time. It also supports sample addition, replacement, and priority testing functions, adapting to diverse and personalized testing scenarios.
