Gas analyzers with an FID (flame ionization detector) are well suited for continuous total hydrocarbon measurement. In the first approach, the measuring result is proportional to the number of C-atoms in the relevant molecule.

The FIDAMAT versions cover a wide range of applications: From trace measurement of hydrocarbons in pure gases - made possible by high resolution and low differences in the response factors - to total content measurement for hydrocarbons in the presence of corrosive gases.

The high, adjustable operating temperature for the internal gas path and the detector also allows the measurement of high-boiling mixtures and the measurement of hydrocarbons at vapour concentrations of up to 100%.  Particular attention has been paid to the safety functions such as automatic start following the warm-up phase, automatic measuring operation and self diagnostis.

The detector flame is automatically re-ignited if accidentally extinguished.  If it does not ignite, a warning message is generated and the gas supply is automatically shut off using a solenoid valve. If the device fails, a purging function prevents the build up of toxic, corrosive or explosive substances inside the device. Fault messages are transmitted via binary output contacts; in addition status messages can be called up individually on the display or via the serial interface.
