has gloss | eng: Fast atom bombardment (FAB) is an ionization technique used in mass spectrometry. The material to be analyzed is mixed with a non-volatile chemical protection environment called a matrix and is bombarded under vacuum with a high energy (4000 to 10,000 electron volts) beam of atoms. The atoms are typically from an inert gas such as argon or xenon. Common matrices include glycerol, thioglycerol, 3-nitrobenzyl alcohol (3-NBA), 18-Crown-6 ether, 2-nitrophenyloctyl ether, sulfolane, diethanolamine, and triethanolamine. This technique is similar to secondary ion mass spectrometry and plasma desorption mass spectrometry. |

has gloss | deu: Fast Atom Bombardment (FAB) ist ein Ionisierungsverfahren, das in Massenspektrometern (MS) benutzt wird. Dabei wird eine Lösung des Analyts in einer flüssigen schwer-flüchtigen Matrix mit einem Partikelstrom aus gewöhnlich inerten Gasen wie Argon oder Xenon (3-8 keV) beschossen. Übliche Matrices sind dabei Glycerin oder 3-Nitrobenzylchlorid. Diese Technik ist nahe verwandt mit der Sekundärionen-Massenspektrometrie. So spricht man von Liquid Secondary Ion Mass Spectrometry (LSIMS), wenn statt Edelgasatomen schnelle Ionen (Cs+, bis zu 35 keV) verwendet werden. |

has gloss | ita: In spettrometria di massa il bombardamento con atomi veloci è una tecnica di ionizzazione per desorbimento, simile allLSIMS. Questa tecnica produce poca frammentazione, è una tecnica di ionizzazione soft. È stata la prima tecnica per lanalisi di grandi molecole, come quelle che si incontrano in ambito biochimico, attualmente questa tecnica è in disuso. |
