Introduction
Instrument of OMS
Tandem Technology
Main Application
anic Mass Spectrometry ( OMS )
Molecular Mass Spectrometry
OMS is a basic and high-technical science.
In which , physics, electronics puter
science were applied to study physical and
chemical character anic molecules
Mass Spectrometry had its origin in early last century
Application anic mass spectrometry for chemical
analysis occurred in early 1940s
Quantitative analysis of hydrocarbon mixtures ( 9 )
produced in catalytic crackers
Methods require time
Fractional distillation , refractive index > 200 hours
Organic mass spectrometry one hour or more
Beginning in the 1950s , chemists have used
anic mass spectrometer for
identification and structural elucidation of a wide
variety pounds
The use of the bined with the NMR
IR and UV revolutionized the anic
chemists went about identifying and determining
the structure anic molecules
Mass Spectrometry
Determine molecular weight
Elucidate structure anic molecule
Identify pounds
Quantify known materials
Accuracy, sensitive and rapid
OMS has been a powerful
analytical tool in modern structure
chemistry and analytical chemistry
