3.1 Field of application and features
3.1.1 Field of application
The FIDAMAT 6 gas analyzer is used for quantitative determination of hydrocarbons.
The measuring principle is based on flame ionization detection (FID). When all requirements
for purity of the zero gas, calibration gas and operating gases are met, the detection limit is
approx. 30 ppb. 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.
Note
The FIDAMAT 6 is designed for continuous operation. Frequent switching on and off (e.g.
daily) can negatively affect the service life of the ignition device and pilot light.
3.1.1.1 Field of application of the FIDAMAT 6-E
Measuring environment
The FIDAMAT 6-E is suitable for measurements of hydrocarbons:
● In the presence of up to 100% water vapor
● With high-boiling components (up to 200 °C)
● In the presence of corrosive gases (with preliminary filter)
● In ultra-pure gas applications
Properties of the device
The FIDAMAT 6-E has the following properties:
● Extremely low cross-sensitivity to interfering gases
● Low consumption of combustion air
The device is also equipped with warning and fault messages, e.g. in case of the following:
● Failure of combustion gas
● Extinguishing of the flame
● Malfunctions of pump and filter
