Product Overview:

The TES-990 fluorescence sulfur analyzer is a sulfur element analyzer that can achieve fully automatic sampling and is widely used to detect sulfur content in liquid, solid, or gas samples. The total sulfur content is determined by UV fluorescence method, and imported components are used in key parts of the system, ensuring reliable performance of the entire machine. The instrument is widely used in departments such as petroleum and petrochemicals, import and export commodity inspection, biopharmaceuticals, environmental protection, health education, and scientific research. The instrument is suitable for measuring the total sulfur/nitrogen content of paraffin oil, diesel, kerosene, gasoline, lubricating oil, fuel oil, liquefied gas and natural gas, as well as other oil products, chemical raw materials and finished products.

Execution standards:

SHT0689-2000 Determination of Total Accurate Content of Light Hydrocarbons, Engine Fuels, and Other Oil Products (UV Fluorescence Method)

GB19147-2016 Determination of total sulfur content of automotive diesel, GB17930-2016 automotive gasoline, light hydrocarbons, engine fuels, and other oil products (UV fluorescence method)

GB/T11141-2014 Determination of Trace Sulfur in Industrial Light Olefins

GB/T11060.8-2012 Determination of total sulfur content by ultraviolet fluorescence spectrophotometry

ASTM D5453-2016,GB/T 34100

Instrument features:

1. Adopting catalyst optimized combustion technology, without the need for an external gas source, enhances portability

2. The gas path has undergone silicon passivation treatment, which makes it super inert to active substances such as sulfur, eliminating the adsorption of samples in the pipeline

3. The host part of the instrument adopts imported products, making the detection lower limit comparable to imported products

4. Imported purification device effectively isolates pollutants

5. UV lights can be set to sleep mode to extend their lifespan

6. Workstation controls heating and cooling temperatures, simple and convenient, accurate temperature control

7. The gas is controlled by a mass flow meter, with precise pressure measurement and alarms for gas leaks and blockages

8. The peak shape can be enlarged and reduced as needed, and the database can be automatically saved for easy retrieval and printing of peak data at any time

9. Optional sequential sampler, no need for manual monitoring, automatic sample injection. The fully automatic sampler adopts a 5.0-inch visual human-machine interactive touch interface (24 bits), expandable 156 bit sample disk, and synchronous injection time reproducibility of less than 1/1000 second (fully automatic liquid sampler is optional)

10. The sample analysis time is less than 1 minute, precise and fast, greatly reducing the analysis time.
