EDX-8800 Alloy Chemical Element Analyzer

The EDX-8800 all-element analyzer is a high-precision spectral analysis instrument based on X-ray fluorescence technology, which is different from the channel-type direct reading spectrometer. It adopts the latest digital multi-channel technology and has the advantages of no argon gas consumption and non-destructive testing of samples. Through the vacuum device, precise multi-element type analysis can be conducted on alloy elements and light elements such as S, P, Si, Mg and Al in various metal materials. Moreover, the operation is convenient and the test results can be directly printed. The X-ray tube emits X-rays to irradiate the sample, and the atoms contained in the sample are excited to produce X-rays specific to atoms. This kind of X-ray is called X-ray fluorescence.

The generation principle of X-ray fluorescence: Different elements have different wavelengths (energies). Qualitative analysis can be carried out by detecting the wavelength of X-ray rays. The intensity of X-ray fluorescence has a functional relationship with its content. Detecting the specific X-ray quantity value of an element can enable quantitative analysis.

Technical advantage

1. Multi-functional sample placement device

A. Sample tray: A measuring device that can rotate automatically. The unit or multi-position automatic sample rotation device can be selected, featuring a sample spin function to reduce the influence of rough and streaks on the sample surface

B. Environment of the sample chamber: Air, vacuum (with vacuum pump), helium (helium-filled pipeline) can be selected.

2. The filter for enhancing sensitivity can be automatically replaced: By using the filter once, the characteristic X-rays and continuous X-rays of the light tube are optimized, and the S/N ratio is improved. It is particularly effective when conducting trace element analysis. And it can be automatically replaced through software.

3. Models pursuing high speed, high sensitivity and high precision: By installing high-resolution SDD detectors and achieving high counting rates, higher detection efficiency can be obtained.

4. Software Functions: Enhance the accuracy of the FP test method without standard samples. Additionally, add the EC multi-standard sample calibration curve method. By determining the standard samples, a calibration curve is created based on the relationship between the X-ray fluorescence intensity and the content of the standard samples, which is a method for quantifying unknown samples.
