WebThe Helium Ionization Detector is a "universal" detector which responds to all molecules except neon. The HID is particularly useful for volatile inorganics like NOx, CO, CO2, O2, N2 and H2 which do not respond on the FID or other detectors. Unlike an FID, the HID needs no hydrogen or air. WebThe present invention relates to an apparatus for detection of ionizing radiation, wherein the incident radiation ionizes a substance, and the electrons released as a result thereof are accelerated in a dual parallel plate electrode arrangement (17, 19, 21). These electrons will interact with a scintillating substance to emit light, which is detected by a position …
