Application range
The gas analyzer FIDAMAT 6_G serves to quantitatively determine hydrocarbons in pure
and ultra-pure gases. The device is not intended for the measurement of corrosive and
condensing gas mixtures.
The measuring principle is based on flame ionization detection (FID). When all requirements
for the purity of the zero gas, test gas and operating gases are met, the detection limit lies at
approx. 30 ppb. When hydrocarbons are burned in a hydrogen flame, ions are formed,
which, in turn, are converted into a current flow when an electric field is applied. The current
strength resulting from this is a measure for the number of hydrocarbon atoms.
Use
The FIDAMAT 6-G gas analyzer is characterized by its use for measuring hydrocarbons in
pure and ultra-pure gases.
As compared to other comparable devices, the FIDAMAT 6-G has:
•
a very low sensitivity to cross-gases
•
low combustion air consumption
•
little influence from oxygen
The device is also equipped with warning and fault messages, e.g.:
•
when the combustion gas fails
•
when the flame goes out
