EXPEC-2000 VOC system is based on the principle of gas chromatography technology(GC-FID),it is of capable monitoring characteristic factors such as methane/non-methane hydrocarbons and benzene etc.
Mercury analyzer applies cold vapor atomic fluorescence technology(CVAFS), integrated with dilution sampling system to eliminate interference with
background components and ensure reliable performance. Automatic calibration of mercury check with internal CAL-200 calibration gas generator.
