«Spectroscan MAKC-GV» desktop x-ray fluorescent crystal diffraction scanning spectrometer is the most universal and modern instrument of «Spectroscan MAKC» brand. It can analyse elements from 11Na to 92U. The range of analysed elements is expanded due to development of vacuum chamber with goniometer and 5 automatically changeable crystal-analysers. The samples are outside the vacuum chamber; therefore any type of samples (solid, liquid, powder) can be analysed. No external cooling systems, no liquid nitrogen, no gas pumping is required. Automatic sample changer for 16 samples has also two cells with spinning, providing representative analysis of heterogeneous samples. High aperture scheme together with 200W x-ray tube provides high intensities of analytical lines, therefore sensitivity and express analysis. Simplicity and flexibility of operation due to a user-friendly interface. Complete computer control of measurements, easy processing (automatic or manual). Quantitative, qualitative and standardless analysis. |
