WebIONISATION –Electron Impact Ionisation (EI) • Operation depends on the conversion of gas molecules into charged particles, typically positive ions / fragments. • Achieved by electron impact ionisation via thermionic emission from a hot filament. • A typical current is 1x10-4Amps. • Ions extracted into the mass filter. WebThe RO-20 AA detector is an air-filled ionization chamber. It has a diameter of 7.32 cm (2.88“) and a volume of 220 cm³ (13.4 in³). The detector has 640 mg/cm² phenolic walls inside a 1.6 mm (0.063”) aluminum wall case for a total thickness of approximately chamber. The shield thickness is approximately 1,000 mg/cm².
