Mass Spectrometer for Qualitative and Quantitative Gas Analysis

Mass spectrometry (MS) is an analytical technique for determining the molecular constituents of pure or mixed gases, vapors, liquids, and even solids. By bombarding the sample with an electron beam, ions are generated and separated according to their mass-to-charge ratio. The resulting mass spectrum is a plot of intensity as a function of mass-to-charge ratio.

BELMASS II is a quadrupole mass spectrometer (QMS), a unique mass analyzer used in mass spectrometry. As a quadrupole, it consists of four cylindrical rods arranged parallel to each other. By applying an oscillating electric field to the rods, the ions are separated based on the stability of their trajectories as a function of their mass-to-charge ratio (m/z). An electron multiplier detects the deflected ions. BELMASS II can be combined with various instruments. Especially in combination with a BELCAT II it can provide important information about the species of the desorbed gases from gas/vapor mixtures and their breakthrough curves.
