Elements |
The cataloged resource
pertains to the properties and reactions
of the main-group elements—the
s and p-block elements, found in columns
one, two, and thirteen through eighteen
of the periodic table. |
| Mass
Spectrometry |
Mass spectrometry is
an analytical technique used to separate
compounds based on differences in their
molecular mass, as well as identify unknown
compounds, quantify known compounds,
and determine the structure and chemical
properties of molecules. Common types
of mass spectrometry (MS) include FAB
(fast atom bombardment), ESI (electrospray
ionization), MALDI (matrix assisted laser
desorption), TOF (time of flight), FT
(Fourier transform), and ICP (inductively
coupled plasma). Mass spectrometry is
also often combined with other analytical
techniques, such as gas chromatography
(GC) and liquid chromatography (LC). |

Science |
Materials science studies
