Cement X-ray Fluorescence Spectrometer Analyzer
Cement X-ray Fluorescence Spectrometer Analyzer
1、 Instrument usage
The analysis of SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, K2O, Na2O, TiO2, P2O5,
Cl and other contents in raw materials, raw materials, kiln feed, clinker and cement
meets the standard requirements of repeatability and reproducibility limits in GB/T176-
2017 Methods for Chemical Analysis of Cement.
2、 Instrument hardware parameters
1. Adopting secondary target technology
(1) The first target material is an X-ray tube;
(2) Target material: Ag target;
(3) Power: Maximum high voltage 50KV, maximum current 1mA;
(4) Focal spot size: less than 150um;
(5) Cooling method: forced air cooling;
(6) The second target material is a fully focused hyperbolic curved crystal, with
germanium crystal as the secondary target, which can effectively excite K-line
systems of elements such as K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, as well as
some heavy metal L-line systems.
2. Monochromatic focusing excitation light path
(1) High throughput fully focused hyperbolic curved crystal (HF DCC) (the whole
machine has obtained national invention patent technology);
(2) Diffraction efficiency: ≥ 10%;
(3) Focusing spot:~500um;
(4) Monochrome efficiency: over 90%
positional deviation, ensuring the stability of the entire machine;
(6) No drift correction is required.
3. SDD silicon offset detector
(1) Resolution: superior to130eV@Fe：Kα6.4KeV；
(2) Window acceptance area: 30mm ²;
(3) Count rate range: 1000cps-100000 cps;
(4) 48 hour peak drift:<1eV @ Fe: K α 6.4KeV.
4. Using hydrogen gas to blow the optical path
No need for cylinder gas and vacuum protection, using hydrogen atmosphere
protection can reduce system maintenance frequency and cost, and stable analysis
data can be obtained in just a few seconds of inflation.
5. Spin device
When measuring samples, the sample rotates around the central axis, and X-rays
scan a large area of the sample to eliminate analysis errors caused by local non-
uniformity of the sample.
6. The X-ray irradiation method is downward irradiation
Stimulate fluorescence to irradiate the sample from top to bottom, avoiding dust
contamination of the light path components and detectors on the sample surface.
7. Sample mouth
(1) The sample preparation methods can include boric acid compression, steel ring
compression, and melt compression;
(2) The maximum diameter of the sample is 40mm.
3、 Instrument software parameters
1. Built in basic parameter method
(1) The basic parameter method eliminates analysis errors caused by differences in
sample matrix and spectral line interference, and only requires a few standard (fixed
value) samples to obtain accurate quantitative results;
(3) Built in non-standard semi quantitative curve, which can rely on standard substances
to establish calibration curves and achieve more accurate quantitative capabilities;
(4) The number of calibration curves established is not limited;
(5) The software function can achieve visualization, with instrument hardware
parameters, instrument sample information, test spectra, and test data displayed on the
same interface, intuitively showing all parameters.
(6) Controlled by computer, operating system is Windows 11;
(7) Operating software to obtain software copyright
