The
Finnigan ELEMENT GD, a combination of a glow discharge ion source with
a high resolution mass spectrometer, is the ultimate tool for the direct
analysis of conductive materials. Almost all elements present in a solid
sample, including carbon, oxygen and nitrogen can be detected and routinely
quantified. Many elements can be analyzed down to the ppt (parts per trillion)
range. The
ingenious and yet simple design of the Glow Discharge Source reduces
sample to sample switching to a fraction of the time it used to be.
The sample itself is placed in a vacuum chamber, completely eliminating
any risk of leaking between the sample and the GD cell. The sample holder
can quickly and easily be removed from the ion source, simply unloaded
and re-loaded, and repositioned for the next measurement. Opening and
closing of the ion source manifold is fully automatic.
