SH407 X-ray Fluorescence Sulfur Anaylzer is specially designed to determine sulfur content in the petroleum products. Adopts energy-dispersive principle, and with electrical, mechanical and microprocessor integration design, so 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.

Instrument characteristics

(1) With electrical, mechanical and microprocessor integration design, so it is compact and beautiful;

(2) It 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) 8-inch (1024*768)capacitive touch screen;

(5) It  can determine its working state and electric parameters by making repeatability test and spectrum scan using reference samples.

(6) Equipped with a RS232 serial port, it can connect with any computer .

(7) It takes disposable sample cell with Mylar film, so it can avoid cross contamination. Sample cell is made by a multifunction pressure shaping device, so it is rapid and convenient. There is a hole on the sample cell cover and you can record sample serial number, S% (m/m), and date on the sample cell cover.

(8) The sample holder is installed on a slide rail,It is convenient and it can avoid any contamination to detection system.

(9) It can save large quantity of test data. You can browse test data and calibration curves at any time.

(10) It uses a thermal printer, so it is easy to replace printing paper.

(11) Tightly protection measures to avoid oil leakage. The sample cell is placed on the leakage protection device. The sample cell can enter into the detection system together with the leakage protection device only during sample analysis procedures. If the instrument is not at sample analysis state, the leakage protection device will move out, so this can avoid any contamination to the detection system.

(12) Its safe X-ray protection measures can keep people from injury of X-ray radiation.
