Technical Description

The ions move in the electric field, generating a current, which is
proportional to the concentration of the ionized molecules in the

ionization chamber. An electrometer circuit converts the current to a
voltage that is then fed to the microprocessor.

After the sample passes through the flame and has become ionized
it is vented from the detector through a flame arrestor. The flame

arrestor prevents the flame from igniting any flammable gases
present in the sampling location.

Detector Response

MicroFID is strictly an organic compound detector. It does not

respond to inorganic compounds. MicroFID’ s sensitivity is highly
dependent on chemical structure and bonding characteristics. The

combustion efficiency of a compound determines its sensitivity.

Simple saturated hydrocarbons (methane, ethane etc.) possess high

combustion efficiencies and are among the compounds that produce
the highest MicroFID response. Organic fuels (acetylene, refined

petroleum products), burn easily and are also extremely well
detected.
