Samenvatting:
Fluorocarbon compounds such as HFCs, PFCs and i.e. SF6 in the Earth'satmosphere contribute
to the greenhouse effect. International and national policy is aimed
at a reduction of these
anthropogenic greenhouse gases. Research is also aimed at the surveillance
of sources of
emissions and determination of the effect of measures taken to reduce
these emissions.
This report is an inventory of possibilities for measuring the changes
in air concentration of
fluorocarbon compounds. This technique will be used to survey these
sources from towers.
After investigating internet and literature a number of techniques is
described and judged for
this purpose and also a number of suppliers of these instruments are
contacted to make possible
a responsible choice and impression of the technique. This iterative
process has lead to a rough
impression and description of an instrument that is composed of a Gas
Chromatograph (GC)
with an Electron Capture Detector (ECD) and a Mass Spectrometer (MS).
Also is stated that the choice of the fluorocarbon compound that has
to be measured will greatly
effect the composition and performance of the instrument.
