Energy Dispersion X-ray Fluorescence Spectrometer TRXS-601after being completely filtered by the optical filter, the original X-ray produced by the X-ray tube and exposed at a high voltage on the sample. It can do qualitative, quantitative, and no sample analysis. Almost all of the elements can be accurately analyzed. The types of elements contained in the sample have been qualitatively analyzed by the position and shape of the spectral peak. Filters are automatically selected and converted. It does not require operators to set multiple test parameters, with a historical query function and test data is automatically saved.
