6. Support LIMS system connection

7. Power supply: AC220V ± 20V, 50Hz; Rated power: 3000W

8. Repetitive error: Measurement accuracy and acceptance requirements: The standard sample of the Institute of Rock Science and Technology is continuously injected 10 times, and the instrument precision (RSD) is ≤ 1mg/L RSD ≤ 8%; ≥ 1mg/L RSD≤5%

5、 Performance characteristics

1. Vertical combustion analysis mode with vertical injection;

2. Ensure the conversion of sulfur, and the SO2 generated after combustion is directly detected by a UV fluorescence sulfur detector;

3. Equipped with ultraviolet fluorescence detector;

4. Equipped with 156 fully automatic liquid injectors: achieving unmanned analysis; Computer control, fully automatic control of the experimental process, automatic replacement of samples, automatic cleaning, automatic elimination of errors caused by bubbles using volume difference method, and automatic drawing of standard curves. The injection speed is constant and can be adjusted according to the sample.

5. Injection volume of 1-80ul;

6. UV lamp: Pulse flashing xenon lamp or zinc lamp is used as the excitation light source, effectively avoiding the instability of sampling values caused by the attenuation of UV lamp signals. The detection lower limit is lower, the detection accuracy is higher, and it can meet the requirements of various oil sulfur content detection;

7. Mass flow meter: The gas flow rate is precisely controlled by the mass flow meter, and the gas flow rate is stable and accurate without fluctuations. The instrument has better repeatability and higher measurement accuracy for small content samples. At the same time, the mass flow meter detects abnormal flow of carrier gas or auxiliary gas, and the system suspends the injection of oil sample to prevent carbon deposition and contamination of the gas path and detector due to sample oxygen deficiency cracking.

8. Gas pressure and temperature are precisely controlled by response sensors;

9. The instrument adopts a low voltage design as a whole, with independent transformers and all components powered by low voltage;

10. Real time monitoring of instrument status by software. In case of abnormalities in gas flow rate, pressure, furnace temperature, etc., the instrument will automatically cool down and enter a protective state to ensure laboratory safety;

11. The reaction chamber is specially manufactured to prevent light and gas leakage, improving the detection sensitivity and repeatability of the instrument;

12. Sleep wake-up function, which can set the combustion furnace temperature, gas flow rate, etc. during sleep. After completing the analysis, the instrument automatically enters sleep mode and can be awakened at any set time;

13. Equipped with a data processing system and automatic calculation function for concentration and content. The software automatically analyzes curves and data without the need for manual switching of injection, ensuring the accuracy of low content samples; Combining single point correction and multi-point correction to automatically generate correction curves.
