Mass spectrometry
Mass spectrometry is an instrumental technique of analysis resting on the separation, identification and quantification of the components of a sample according to their mass. Thus atoms, molecules or aggragates are extracted in the form of ions, then sorted by a dispersive system: sector of electric or magnetic field, quadripolar filter or time of flight.

The mass spectrometry is an instrumental technique of analysis resting on separation, the identification and the quantification of the components of a sample according to their mass. It is founded on the coupling of a plasma generating ions and of a quadrupolar mass spectrometer (in the case of the ICP-MS Thermoelectron X7) which separates these ions in mass.
The ICP-MS analysis of the samples can be divided into four stages: introduction-atomizing, ionization, separation in mass, detection.
