ION SOURCES USED IN MASS SPECTROSCOPY Approximate Source Type
Primary Use Spread in Ion Special Requirements Energy Gas discharge (1)
Packing fractions ~1,000 volts For most purposes double focusing mass
spectroscope.
Mark Gordon Inghram, Richard J. Hayden, 1954
Smith,"-19 at the Brookhaven National Laboratory, has employed a completely
different type of mass spectroscope known as the “mass synchrometer.” Here the
ions describe circular paths in a homogeneous magnetic field, the frequency of ...

Theirs is also a tremendous instrument, used for the quantity separation of
isotopes. Paul and Maether have successfully used an ac electric field only as a
mass spectroscope. Their ion beam follows a trajectory down a quad— rupole
field.

In order to assess the nature of the fuel species available for the SOFC of the
ethanol flame, the compositions of the ethanol flame were experimentally
analyzed by a micro-quartz tube probe in connection with a mass spectroscope.

spectroscope separates isotopes of the same element based on differences in
their mass.
The ions so produced are accelerated and mass analyzed in a mass
spectroscope. Ion detectors can, of course, be photographic or electrical." Since
the ion beam is inhomogeneous in energy, a spark source can be used only with
a double ...
