The analytical technique of mass spectrometry has a broad range of uses including to identify unknown compounds within a material, measure the amount of a known material that is present in a sample, and to measure changes in sample composition in real time. Mass spectrometry is applied to solids , liquids, gases and vapour.

The measurement of changes to gas and vapour composition in real time extends the application use of mass spectrometry to applications in fuel cells, catalysis, plasma, environment and electro-chemistry.


Mass Spectrometer Components

Every mass spectrometer consists of three basic components; the ion source, the analyzer, and the detector system.

The ion source is used to generate the gaseous ions from the sample, which are required to perform the measurement. The analyzer is used to separate the different types of ions according to their mass-to-charge ratio, and the detector reads these ions and records the amount in each group.

Mass Spectrometer Process

The first part of the process within a mass spectrometer is ionization, and this occurs when an atom within the sample gains a negative or positive charge. Most standard mass spectrometers work with positive ions.

Once the ions are generated, they are all accelerated to ensure they all have the same kinetic energy, and they are then deflected by a field according to their mass-to-charge ratio to filter the ions into a detector.
