Energy dispersive X-ray fluorescence (EDXRF) spectrometer for sulfur analysis in petrochemical products
U-Therm International (H.K.) Limited
Electromechanical integration; microprocessor control; large screen LCD display; Man-machine conversation; simple and beautiful;
It can determine various products and in a wide measurement range. It is rapid for analysis and it only need little standard sample.
It has self-diagnostic function, so it can determine its working state and electric parameters.
It 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.
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.
Main technical parameters:
Measurement range: 7 ppm to 5%;
Precision: Repeatability: <0.029 ( S+0.6), Reproducibility: <0.063 ( S+0.6);
Sample quantity: 2 to 3 ml (it is equal to sample depth of 3 mm to 4 mm);
Measurement time: 60, 120, 240, 300, and 600 s at random;
It can make determination automatically for single sample. Measurement times: can set 2, 3, 5, 10, and 50 times at random; it will show average value and standard deviation at end of measurement.
Calibration curve numbers: it can save 9 calibration curves. 5 pieces of them are linear equation in one unknown and 4 pieces of them are binomial parabola.
