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.

*Benchtop quadrupole mass spectrometer

*Heated hose enables the analysis of vapors

*Instrument with built-in mass spectrometer and vacuum pump

Combination with BELCAT II catalyst analyzer

The combination of the BELMASS II mass spectrometer with the BELCAT II makes it possible to evaluate the catalytic reaction (TPReaction)

in more detail. BELMASS ll can record the sample temperature and is suitable for thermal analysis.

OVERVIEW

The mass detector is recognised to be the most efficient detector for qualitative analysis. However, it is difficult to obtain

a good quantitative result because it analyzes only a small amount of gas.

By selecting the most suitable materials and components, Microtrac MRB has successfully developed the mass spectrometer

BELMASS II with a high quantitative capacity. Even ammonia gas can be analyzed by using a heated hose and a dry diaphragm pump.
