Mass Spectrometer THR-G DMS High resolution Glow Discharge Mass Spectrometer OEM

The domestically produced THR-GDMS instrument adopts a slow flow glow discharge ion source and is equipped with needle shaped and sheet-like sample racks, which can be used for material analysis of conductors, semiconductors, insulators, powders, coatings, and other materials. The structural design of liquid nitrogen cooled ion source makes it easy to analyze low melting point metals such as gallium. Specially designed gas purification device and vacuum internal baking minimize the background of C, N, and O gas elements. The instrument adopts a forward Neil Johnson structure with a mass dispersion of 570mm, and is designed with three levels of resolution (400/400/10000 (10% peak valley definition) for fast switching of slits. The magnetic analyzer adopts magnetic field measurement closed-loop control to eliminate the influence of hysteresis effect on the accurate setting of mass number. The detection system is equipped with Faraday cup, electron multiplier simulation method, and counting method, and the instrument has a linear dynamic range of up to 1012 orders of magnitude.
