NPO Spektron

The spectrometer is designed to determine the contents of elements in the range from Ca to U in substances in solid, powdery, dissolved states, as well as deposited on the surface or deposited on filters. The principle of operation of the spectrometer is based on irradiation of the sample with primary radiation from an X-ray tube, measurement of the intensity of secondary fluorescent radiation from the sample at wavelengths corresponding to the elements being determined, and subsequent calculation of the mass fraction of these elements according to a pre-constructed calibration characteristic, which is the dependence of the content of the element being determined on the measured intensity. Secondary fluorescent radiation is decomposed into a spectrum using a crystal analyzer. Due to this, the spectrometer has a high resolution, and therefore the ability to accurately analyze complex multicomponent substances.

The X-ray fluorescence spectrometer SPECTROSCAN MAX-GF1(2)E-C combines two methods of detecting an analytical signal: diffraction on a crystal (wave dispersion - WDX) and energy dispersion (EDX) method, as well as sample delivery adapted for the analysis of large-size images. The collimation of the primary radiation of the X-ray tube and the special design of the sample presentation make it possible to analyze the sample over an area of 1 cm2 in 1 mm increments, and thus investigate the distribution of elements over an area.
