2 Application
The FIDAMAT 5E is an analyzer for measuring total hydrocarbons. It operates according to the
principle of flame ionization.
The analyzer is suitable for measuring all gaseous hydrocarbons. A heated line must be used for
the connection to prevent condensation and adsorption in the gas line.
Warning! Explosivegasmixturesmust not bemeasuredusingtheFIDAMAT.The ana-
lyzermustnotbeusedinpotentiallyexplosiveatmospheres.

3 Design
The device is available either as a bench-top unit fitted in a housing, or without a housing for
installation in a 19-inch rack or 19-inch cabinet.
TheFIDAMATcomprisestwomainsections,theanalyzersectionandtheelectronicswithfrontpanel
controls.
Analyzersection
The analyzer section consists of the oven with sample gas filter, detector chamber and various
restrictors.The ovenis accessiblefrom thesideto enablemodifications orrepairs tobe carried out
in the installed condition without loosening the electric connections or gas piping connections.The
sample gas filter is accessible from the front when the front panel has been folded out.
The analyzer section also contains the diaphram pump with separate oven for the pump head.The
pump can be dismounted from the front without having to open the oven.
The analyzer section also contains pressure regulators, solenoid valves, pressure sensors and a
flowsensor.
Electronics
The electronics consist of the input board which is integrated into the front panel, the motherboard
with preamplifier board and the control board.
Themotherboard contains theEPROMs forthe software, theEEPROM for theparameter sets and
the switch for the write-protected area on the EEPROM.

4 Mode of Operation
Electrons are released when hydrocarbons are combusted in a hydrogen flame. These electrons
are collected at an electrode by means of an electric field and measured using a highly sensitive
amplifier. The current is proportional to the quantity of organically-bound C atoms in the sample
gas.
A diaphram pump draws the sample gas and generates a specific pressure. The sample gas is
passed into the measuring chamber via an obstruction-resistant fused silica restrictor.Thesample
gasismixed in themeasuring chamber withhydrogenorhydrogen/helium (4:6)and with a specific
amount of air and routed via the nozzle into the combustion chamber.
The hydrogen pressure is held constant by a pressure regulator. The balanced system of pump,
restrictors and pressure regulators ensures that the sample gas pressure is kept constant.
TheFIDAMAT operates largelyautomatically. Iftheparameters (pressures,temperatures) areset,

been reached. The hydrogen and combustion air pressures are measured when switching on, and
the control panel indicates if they are incorrectly set.
