The analytical technique of mass spectrometry has a broad range of uses that include, for example, identifying unknown compounds within a material, measuring the amount of a known material that is present in a sample, and measuring changes in sample composition in real time. Mass spectrometry is applied to solids, liquids, gases and vapors.

The measurement of changes to gas and vapor composition in real time extends the use of mass spectrometry to applications in fuel cells, catalysis, plasma, environmental 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 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 collects these ions and records the amount in each group.

Mass Spectrometer Process

The first part of the process within a mass spectrometer is ionization; 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 accelerated to ensure they all have the same kinetic energy, following which they are deflected by a field according to their mass-to-charge ratio to filter the ions into a detector.
