Xrf Total Sulfur Tester, ASTM D4294

GD-17040 XRF Total Sulfur Tester
PurposeGD-17040 XRF Total Sulfur Tester is specially designed to determine sulfur content in the petroleum products. Adopts energy-dispersive principle, and with integrated design, it is rapid and accurate. It can meet the requirements of National Standard GB/T 17040 and GB/T11140 on repeatability and reproducibility, and it can also meet requirements of ASTM D4294-03 on these indexes. It provides a measure to determine sulfur content during petroleum or petrochemical production process.Features:1. GD-17040 XRF Total Sulfur Tester can be used to determine mass% of total sulfur in the crude petroleum, petroleum, heavy oil, diesel oil, gasoline, and naphtha.2. GD-17040 XRF Total Sulfur Tester can be used to determine total sulfur content in the products of coal chemical industry, such as primary benzene.3. GD-17040 XRF Total Sulfur Tester can be used to determine total sulfur or sulfide in other liquid or solid powder samples.
Instrument characteristics:1. Electromechanical integration; microprocessor control; large screen LCD display; Man-machine conversation; simple and beautiful;2. GD-17040 XRF Total Sulfur Tester can determine various products and in a wide measurement range. It is rapid for analysis and it only need little standard sample.3. Adopts fluorescence intensity ratio analysis methods, it can make correction to temperature and pressure automatically and it can also make correction to ratio of carbon and hydrogen (C/H).4. GD-17040 XRF Total Sulfur Tester has self-diagnostic function, so it can determine its working state and electric parameters.5. GD-17040 XRF Total Sulfur Tester takes disposable sample cell with Mylar film, so it can avoid cross contamination. Sample cell is made by a multifunction pressure device, so it is rapid and convenient. It can record sample serial number, S% (m/m), and date.6. The sample holder can be precisely located. It can move out from inside of the instrument for sample location and anti-leakage parts replacement. It is convenient and it can avoid any contamination to detection system.7. It can save large quantity of test data. You can browse test data and calibration curve at any time.8. It uses a thermal printer, so it is easy to replace printing paper. It is needed to speed money on printing ribbon.9. Equipped with a RS232 serial port, it can connect with any computer or web system.10. Its safe X-ray protection measures can keep people from injury of X-ray radiation.
