desorption ionisation

A general term used for mass spectrometry methods in which ions are generated directly from a sample by rapidly inputting energy into the condensed phase sample (e.g., secondary ion mass spectrometry, fast atom bombardment, californium fission fragment desorption, and plasma desorption). There may be no discrete thermal desorption, but rather a transfer of nonvolatile sample molecules into the gas phase as ions for subsequent analysis.

The IMPACT Dx system identifies numerous analytes in a DNA sample using matrix-assisted desorption ionisation time-of-flight (MALDI-TOF) mass spectrometry.
The recommended tests include Dutch Qiagen's (ETR:QIA) Therascreen KRAS RGQ PCR Kit, German TIB MolBiol's KRAS LightMix Kit, as well as the methods pyrosequencing of codons 12, 13 and 61, and MALDI-TOF (matrix-assisted laser desorption ionisation time-of-flight) mass spectrometry of codons 12, 13 and 61.
