Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

Mass spectrometry (MS) is an analytical technique that ionizes chemical species and sorts the ions based on their mass-to-charge ratio. Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry which is capable of detecting metals and several non-metals at ... isotope Of Ca at mass 40.

An Introduction to Mass Spectrometry

Data System Mass Detector Analyzer Vacuum System Source Inlet Region *More precisely mass spectrometry determines the mass of a molecule. **The mass to charge ratio ( m/z) is used to describe ions observed in mass spectrometry.By convention, m is the numerical value for the mass of the ion and z is the numerical value for the charge of the ion.

The mass spectrometer gives the mass to charge ratio (m/z), therefore the sample (analyte) must be an ion. Mass spectrometry is a gas phase technique- the sample must be “vaporized.” Electron-impact ionization Sample Inlet 10-7 - 10-8 torr R-H electron beam 70 eV (6700 KJ/mol) e_ R-H + mass analyzer m/z ionization chamber (M+) proton 1 ...
