sexCharacteristics of Ability：

1Quartz cracking tube:Blind quartz tube ensures full combustion of the sample through back and forth combustion, without the need for tungsten trioxide as a catalyst, which can also fully convert the sample and avoid carbon deposition.

2. Gas path stabilizing device:The installation of a pressure stabilization system in the gas circuit avoids interference from gas flow and pressure fluctuations on the measurement.

3. Gas flow control: Using electronic mass flow meters and computer-controlled gas flow, the gas flow rate is stable, accurate, and 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 workstation suspends the injection of oil samples to prevent carbon deposition and contamination of the gas path and detector due to sample oxygen deficiency cracking.

4Temperature control:Delayed air cooling technology allows the instrument to be shut down directly after analysis is completed, without waiting for the cracking furnace to cool down to room temperature before shutting down, saving analysis time.

Equipped with error warning function during operation and the ability to prohibit sample injection due to errors;Equipped with over temperature automatic power-off protection function.

5. UV Fluorescence Detector (UVFD): Using imported coating materials and advanced spraying technology, it ensures the airtightness of each component, no air leakage, no light leakage, and minimal external interference. The background noise in the detection room is lower, improving the sensitivity and detection limit of the instrument.

6. Key components: UV lamps, monochromators, membrane dryers, photomultiplier tubes, etc. are all imported products

7RPP-9000B UV Fluorescence Sulfur AnalyzerUsing a vertical fully automatic sampler,The injection speed is constant and can be adjusted according to the sample, greatly reducing the system detection error caused by human error in sampling and improving the detection accuracy of the instrument. The parameter settings of the injection system are all completed in one go on the computer, and users do not need to separately set the injector. After the user completes the sampling and starts the detection, the system can enter unmanned operation, reducing the intensity of operators and improving work efficiency. Users can add new test samples or replace already tested samples during the testing process of a batch of samples, expanding the number of detection bits of the sampler. If the user has a sample that needs to be tested immediately, the sample can be set as a priority for testing. Users can also place standard samples at the desired bottle positions, and the system can automatically correct the system curve deviation based on the test results of the standard samples.

8. A single silicone pad ensures that the number of injections is above 500, reducing the frequency of silicone pad replacement and improving the detection efficiency of the instrument.

9、Adopting a replaceable needle type injection needle: ensuring that the sample is fully burned at the optimal combustion position and avoiding carbon deposition.

10workstationReal time monitoring of instrument status,gas flow rate、cracking furnaceFurnace temperature, gas pressurePMTHigh voltage, baseline, and other states,When an abnormality occurs, the instrument automatically alarms and cools down to enter a protective state, ensuring laboratory safety.

The analysis process and data processing process are computer-controlled, easy to operate, equipped with a data processing system, and have automatic calculation functions such as concentration, content, unit conversion, RSD, etc.

11. Energy conservation and environmental protection: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, allowing the instrument to complete self inspection and enter working mode without the presence of the operator.

Adopting a low-power integrated circuit system, all internal circuits use low-power components such as CPUs, A/D conversion modules, etc. The STC series low-power version is used to reduce the overall instrument power consumption and achieve the goal of low power consumption after long-term use.

12. System for eliminating nitrogen interference: When the nitrogen content is ≤ 2000ppm, it has no effect on the determination of sulfur element.

13. High purity oxygen can be used as the gas source（99.99%）High-purity argon gas（99.99%）Or use an air generator instead of steel cylinder gas to save usage costs.
