«Express» universal spectrometer
The spectrometer we produce are coming with MAES analysers in accordance to analytical task.
Systems based on the spectrometers that we produce are a measuring devices for a fractions of total mass of detected elements of substances and materials (№ 33011-06 in Russian state registry of measuring devices).
The delivery set consists of spectrometer with MAES preinstalled in it, stand with arc/spark semiconductor generator, a computer, a table and a chair, printer stand, and some additional equipment as well - probe preparation machine, calibration probe sets for initial setup and routine control, etc.
To eliminate temperature changes, excess light and dust, spectrometers can be equipped with a special protective case. Inside of such case there is a dust-catcher and a noiseless fan, which creates an excessive air pressure and a ventilation of an inside area.
This spectrometer is designed to perform direct qualitative and quantitative spectrum analysis of different substances and materials (powders, metals, liquids) in industrial and research labs.
"Express" is distinguished for its compact size thanks to vertically placed optical Paschen–Runge scheme. Based on nonclassical concave diffraction grating with two MAES analysers 10 photodiode arrays each. Arrays are forming 520mm radius. Express comes with special table with the built-in computer and the spectrum excitation source.
