mass spectrometer

n.
A mass spectroscope that records its data electronically.

mass spectrometry n.

mass spectrometer

or

mass spectroscope

n
(General Physics) an analytical instrument in which ions, produced from a sample, are separated by electric or magnetic fields according to their ratios of charge to mass. A record is produced (mass spectrum) of the types of ion present and their relative amounts

mass′ spectrom′eter


n.
a device that uses deflection of ions in an electromagnetic field as a basis for identifying the kinds of particles present in a substance.

The method involves shooting a laser at the sample's surface, which creates a plume of molecules and ions that can then be analyzed by the mass spectrometer.
So you can bring the mass spectrometer to a sample under water, instead of vice versa.

Because the detector has often been the component which limits, and thus defines, the performance of a TOF mass spectrometer, it is expected that the MagneTOF will facilitate a major advance in TOF mass spectrometry.
Hitachi High-Technologies added electron capture dissociation to its LC-IT-TOF system via a module on the front end of the mass spectrometer. It will be available in a complete system priced at around $490,000, which compares with $450,000 for the base model.
The instrument consists of a miniature mass spectrometer combined with a technique called desorption electrospray ionization, or DESI.
