Eight technical advantages：
First, FP basic parameter method
The FP (Basic Parameters) algorithm is an effective method for X-ray fluorescence spectrometry analysis. It can perform qualitative and quantitative analysis of the elemental components of the sample with little or no standard sample, and can also analyze the thickness of the coating or coating.It is well known that the biggest problem with X-ray fluorescence analysis is that elemental fluorescence intensity is affected by coexisting elements (matrix absorption and enhancement effects) and is not usually linear with content. The basic parameter method has already taken into account the matrix effect in the calculation of the spectrum, and the linear relationship between the calculated content and the known content can be obtained. Using a few known sample calibration algorithms to eliminate systematic errors can achieve accurate quantitative results.
Second, polarization secondary target excitation technology
The polarization secondary target excitation technology can remove the scattering background to the maximum extent, improve the signal to noise ratio, and reduce the detection limit of the detector. Assuming that the x-ray generated by the anode of the x-ray tube is non-polarized and is incident on the target (scattering body) in the z-axis direction, the scattered beam propagating along the y-axis is linearly polarized light. The electric field vector vibrates in the v plane and the vibration direction is parallel to the X axis. The sample placed on the y-axis is excited by polarized light, producing unpolarized fluorescent x-rays. Since the sample and the sample support do not generate scattered radiation in the X-axis direction, placing the detector on the x-axis can fully utilize the polarization effect and reduce the background caused by the elastic and inelastic scattering of x-rays.
Third, ultra-short optical design
From the X-ray generator to the sample, the X-ray fluorescence emitted by the sample to the detector is called the light path. The shorter the distance traveled by the optical path is, the less interference will be caused. Skyray Instrument designed an ultra-short optical path technology to ensure the accuracy of light element detection results, and is particularly suitable for RoHS-compliant halogen-free instruction detection.
Fourth, precision machinery design
The micro-level positioning, micro-scanning analysis, the point-to-point centering of the spatial micro-sized spot and the determination of the spatial micro-focus spot position have been truly achieved. A translation and rotation switching position device realizes position rotation switching in a small space, avoids the large space required for the linear motion and the common rotation movement, because the problem of lengthening of the optical path caused by the inability to fit is eliminated.
Five, no standard technology
XRF test and analysis instruments are generally used for the comparison test of standard samples, which are subject to the quality of the standard samples during the test. Tianrui Instrument's original non-standard technology can carry out all-element analysis without standard samples, leading the development trend and trend of the industry.
Sixth, secondary target excitation technology
XRF test and analysis instruments are generally used for the comparison test of standard samples, which are subject to the quality of the standard samples during the test. Tianrui Instrument's original non-standard technology can carry out all-element analysis without standard samples, leading the development trend and trend of the industry.
VII. Signal to Noise Enhancement Technology
Skyray's unique SNR enhancement technology can effectively remove noise signal interference and minimize element detection limits.
As shown in Figure SUPER XRF 1050, the determination of Pb in food can be as low as 0.59 ppm.
