Subject field(s)
  • Physics
  • Analytical Chemistry
CONT

Tandem mass spectrometry... is a process by which gas-phase ions of an analyte resulting from an initial ionization undergo separation according to their m/z [mass-to-charge ratio] values, using a first iteration of mass spectrometry. Ions of individual m/z values(precursor ions) are then subjected to collisional activation so that these precursor ions will fragment, producing product ions of different m/z values. These product ions then are separated and detected by a second iteration of mass spectrometry; thus the name tandem mass spectrometry or MS/MS.

Key term(s)
  • MS-MS

French

Domaine(s)
  • Physique
  • Chimie analytique
CONT

La SM/SM désigne une spectrométrie de masse où un premier analyseur sert à isoler un ion parent qui subit ensuite une fragmentation donnant des ions fils et fragments neutres. Les ions fils sont ensuite analysés dans un deuxième analyseur.
