You hurry into your chemistry lab only to find your teacher slumped unconscious over the lab table. The only Mass spectrometry is a powerful analytical technique that is used to identify unknown compounds. Even with . fragments of an organic compound in a mass spectrometer, we will see major peaks representing the
The result of a Mass Spectrometry is a graph plotting mass per charge against relative abundance. Objects (atoms or groups of atoms) of different masses may be detected due to varying atomic masses giving Isotopes and the fragmentation of molecules into smaller groups of atoms. This data can then be used to calculate
These statements are about the use of mass spectra in identifying organic compounds. Before you go on, you should find and read the statements in your copy of the syllabus. Fragmentation patterns. Start by reading about fragmentation patterns on this page in the Mass Spectrometry section of Chemguide. You might want
Explains how the molecular ion peak in a mass spectrum can be used to find the relative formula mass or the molecular formula of an organic compound. These fragments produce the familiar stick diagram. Fragmentation is irrelevant to what we are talking about on this page - all we're interested in is the molecular ion.
Explains how the M+2 peak in a mass spectrum arises from the presence of halogen atoms (chlorine or bromine) in an organic compound. on this page have been drawn using data from the Spectral Data Base System for Organic Compounds (SDBS) at the National Institute of Materials and Chemical Research in Japan.
7 May 2015 Mass spectrometry allows us to measure the masses of atoms and molecules, and also obtain information about their chemical structure. The graphic shows a range of different fragment ions that can be produced by organic compounds; it's worth noting that fragments that are isomeric with those shown
THE MASS SPECTRA OF ELEMENTS. This page looks at the information you can get from the mass spectrum of an element. It shows how you can find out the masses and relative abundances of the various isotopes of the element and use that information to calculate the relative atomic mass of the element. It also looks at
When the vaporised organic sample passes into the ionisation chamber of a mass spectrometer, it is bombarded by a stream of electrons. These electrons have a high enough energy to knock an electron off an organic molecule to form a positive ion. This ion is called the molecular ion - or sometimes the parent ion.
