General Description
DataFID is a portable flame ionization detector (FID) that detects total volatile organic compounds (TVOCs) for leak detection and repair (US EPA Method 21) both in industrial settings and in the field.
Technical Description
DataFID uses flame ionization detection (FID) to measure total volatile organic compounds (TVOCs) in air at part per million (ppm) or part per billion (ppb) levels. When the DataFID hydrogen flame is ignited, the internal pump draws in air through the inlet, which provides the oxygen necessary for combustion. When the proper hydrogen-to-air ratio is present in the combustion chamber, a glow plug will automatically ignite the flame. TVOCs are ionized when the sample passes through the flame. These ionized molecules are subjected to a continuous electric field; the ions moving in this electric field generate a current that is proportional to the concentration of the ionized molecules in the combustion chamber. An electrometer circuit converts this current to a voltage which is sent to the microprocessor, and is displayed on the front panel as a concentration.
