Mass spectrometer
From Mass Spec Terms
Orange Book Entry
An instrument in which the beams of ions are separated (analysed) according to the mass/charge ratio and the ions are measured electrically.
Proposed New Entry
The mass spectrometer is an instrument with which the chemical composition of material can be analyzed.
Mass spectrometers are considered to consist of three parts:
1) Sample preparation & ionization: for bringing the analyte in gas phase and in charged state
2) Mass analyzer: instrument with which the physical quantity mass/charge of charged particles is measured.
3) Data system: hardware and software for processing the data received from the mass analyzer.
