Nist mass and fragment calculator
Webb13 jan. 2016 · To obtain information beyond the molecule mass, the analyte is usually fragmented, and masses of fragment ions are recorded. The two “standard” experimental methods for small molecule fragmentation MS are gas chromatography MS (GC-MS) using electron ionization (EI) fragmentation, and liquid chromatography (LC-MS) with … WebbThis time the base peak (the tallest peak - and so the commonest fragment ion) is at m/z = 57. But this is not produced by the same ion as the same m/z value peak in pentane. If you remember, the m/z = 57 peak in pentane was produced by [CH 3 CH 2 CH 2 CH 2] +.

WebbCharacteristic Mass Spectral Fragmentation. In mass spectrometry, organic molecules that are present in the gaseous state are bombarded with a beam of energetic electrons (70eV). During bombardment pressure is maintained between 10-7 to 10-5 and electrically heated tungsten or rhenium filament is used for producing beam of electrons.
