Product Description

Item:  Ultraviolet Fluorescence Sulfur, Nitrogen-in-Oil Analyzer
Model:  PT-SYD-0689N

The instrument is designed and manufactured according to the requirements of the industry standard SH/T 0689-2000 of the People's Republic of China "Light hydrocarbon and engine fuel and other oil total sulfur content determination method (ULTRAVIOLET fluorescence method)", SH/T 0657-2007 "liquid petroleum hydrocarbon trace nitrogen determination method oxidation combustion and chemiluminescence method". It can be widely used in petroleum, chemical industry, electric power, coal, food, environmental protection and other fields. It is an advanced sulfur and nitrogen analysis instrument in China.

Meet the standards:
Sulfur: ASTM D5453, D6667, D7183, GB/T 17930, GB/T 11060, SH/T 0689 and other standards.
Nitrogen: ASTM D4629, D5762, GB/T 17674, SH/T 0657, 0704 and other standards.

Technical characteristics
1. Windows Chinese operating platform, computer control analysis, data processing and other processes, display the working status of the whole process; test parameters and results can be saved or printed; historical data query and graphic playback can be realized, which is convenient for comparison and analysis.
2. One needle injection, simultaneous detection of sulfur and nitrogen, the two test results can be detected at the same time, the analysis speed is fast (2-3min/sample), the analysis is accurate and stable, and the repeatability error is far better than SH/T 0689, SH /T 0657 analyzes the error requirements.
3. The core detector of the instrument is manufactured with the patented technology of preventing light leakage and air leakage, so that the instrument has the advantages of high sensitivity, low noise, wide linear range, and strong anti-interference ability.
4. Core components: membrane dryer, filter, xenon lamp, photomultiplier tube, injection needle, filter membrane and other main accessories are original parts imported from the United States, Japan, and Europe to ensure the quality of the instrument and the accuracy of the analysis results , The performance of the whole machine has reached the international advanced level, superior to similar domestic products, and can replace imports.
5. Imported xenon lamp xenon lamp (Japan) is used as the ultraviolet pulse light source, the light intensity is stable, the attenuation is slow, and the service life is long. It overcomes the shortcomings of the traditional UV lamp with fast attenuation and short service life. The cost is not increased, and the service life is extended to more than 5 years. , Good stability ensures the accuracy of detection, while greatly reducing maintenance costs.
6. The instrument adopts international popular circuits and imported components, which reduces instrument noise and improves detection sensitivity.
7. The high pressure can be adjusted arbitrarily, and the standard sample calibration adopts single-point calibration, which is convenient, fast and accurate.
8. Using electronic ozone generator, the amount of ozone generated can be adjusted, which can meet the detection of large-content nitrogen.
9. Using imported high-quality heating wire, the cracking furnace has a longer service life.
10. With delayed shutdown function, after the experiment, the time can be set to automatically shut down, let the cracking furnace cool naturally, and automatically shut down when the time comes, which overcomes the shortcomings of manual waiting in the past.
11. Instrument calibration: The instrument is calibrated with standard samples imported from the United States and Japan to ensure the accuracy of the instrument's measurement.
12. Database management mode: Open lims database management mode, which is convenient for database retrieval and management.
13. Optional solid sampler; solid sampler is equipped with a refrigeration system.
14. Optional nitrogen digester to eliminate high nitrogen interference and meet high nitrogen and low sulfur detection.

Technical parameters and indicators
1. Measuring range: 0.1mg/kg~10000mg/kg~%(S)
0.1mg/kg~10000mg/kg~%(N)
2. Lower detection limit: 0.05mg/kg (S), 0.1mg/kg (N)
3. Measurable samples: solid, liquid, gas (optional for nitrogen digester and sampler)
4. PMT high voltage range: DC400V~900V
5. Correlation coefficient of standard curve≥0.999
6. Temperature control range and accuracy: room temperature~1300ºC, ±1ºC
