Combining the advantages of glow discharge and high resolution mass spectrometry, it has outstanding performance in the following aspects:
 
-High sample test flux: the design of ELEMENT GD ion source and sample clamp can shorten sample change and analysis time and significantly improve productivity;
 
-Wide linear range of the detector: the linear range of the detector reaches 12 orders of magnitude, and the matrix and trace element composition can be detected simultaneously by one scan;
 
-Low, medium and high resolution slits with fixed width, and high resolution can be used to directly analyze isotopes with mass spectrometry interference.
