Note
Differences in the method of operation for the device versions
Unless stated otherwise, the description relates to both device versions of the FIDAMAT 6.
The measuring principle is based on flame ionization detection (FID) with a detection limit of
approximately 0.1 ppm. During the combustion of hydrocarbons in a hydrogen flame, ions
are formed that are in turn converted into a current flow by the application of an electric field.
The resulting amperage is a measure of the number of carbon atoms.
The FIDAMAT 6 measures specific to the substance class, not component-specific. It
measures the total of all organically bound carbons in a sample gas, however with different
weighting of the hydrocarbon molecules.
