RPP-5000SN sulfur and nitrogen analyzer

Product Description:

Sulfur and nitrogen analyzer: The total sulfur content is determined by UV fluorescence method, and the total nitrogen content is determined by chemiluminescence method. The instrument can simultaneously detect total sulfur and total nitrogen, or detect total sulfur or total nitrogen separately. It has the advantages of high sensitivity, low noise, wide linear range, strong anti-interference ability, high analysis accuracy, easy operation, and stable and reliable results.
The instrument is used for the determination of total sulfur and total nitrogen content in crude oil, hydrocarbons, engine fuels, petroleum gas, and petrochemical products.

Applicable standardsSulfur: SH/T 0689、GB/T11141、GB/T11060.8、ASTM D5453；

Nitrogen: SH/T 0657、SH/T0704、GB/T17674、ASTM D4629、ASTM D5762 、ASTM D6069

Main configurationSulfur and nitrogen analyzer host, temperature control system, sampler, computer, etc.

Key componentsImported components are used for zinc lamps, filters, photomultiplier tubes, and membrane dryers.

2. Gas source requirement: Oxygen purity of 99.999%; Argon purity 99.999%
3. Gas flow control: needle valve with rotor flowmeter
4. Analysis time: 2min
5. Support LIMS system connection
6. Power supply: AC220V ± 20V, 50Hz; Rated power: 3000W

7. Measurement range: 0.1-10000ppm

8. Repeatability error: When the concentration of the sample (standard sample) is less than 1.0ppm, Cv≤10%； When the concentration of the sample (standard sample) is ≥ 1.0ppm, Cv≤5%

Performance characteristics：

1. It can measure sulfur and nitrogen simultaneously, or measure sulfur or nitrogen separately.

2. The sulfur and nitrogen analyzer is a high-tech product in Jiangsu Province, with independent intellectual property rights. It has obtained one invention and three utility models.

3. The quartz cracking tube is made of imported high-purity quartz material to reduce the generation of carbon deposits.

4. The exhaust ozone depletion device adopts high-temperature pyrolysis physical method instead of traditional activated carbon adsorption, which fully decomposes ozone and has a fast speed.

5. Combining single point correction and multi-point correction to automatically generate correction curves. Automatically judge the accuracy and repeatability of experimental data according to standards.

6. The linear relationship discrimination of low concentration curves 1, 3, 5, 7, and 10 (mg/L) is high, and the detection results of samples below 10ppm are comparable to imported instruments.

7. Selecting a quality flow meter, computer-controlled, stable flow input, and reducing the problem of large repeatability and reproducibility deviations caused by flow fluctuations.
