Display . The Ecochem PAS analyzer is used to obtain continuous real time data for particle-bound PAH for the purpose of air quality assessment or air quality trend reporting. This procedure is specific to the PAS and should not be applied to other PAH analyzers. Ambient air applications for the PAS analyzer include. The PAS Operation Manual contains a significant source of information pertinent to the operation, maintenance and understanding of this instrument, and therefore the AQSB highly recommends a thorough review of the PAS Operation Manual. Principle of Operation The PAS aerosol sensor is based on the photoelectric ionization of.
OPERATING MANUAL PAS PERSONAL AIR SAMPLER June Haven Avenue Redwood City, CA USA Fax E-mail spectrex@www.doorway.ru The PAS works on the principle of photoionization of particle-bound PAH. Using a nm excimer lamp, the aerosol flow is exposed to high-intensity, narrow band ultraviolet radiation. EcoChem. - Model PAS CE -. Compact Real-Time Photoelectric Aerosol Sensor. The PAS works on the following principles: Using an Excimer lamp the aerosol flow is exposed to UV radiation. The Excimer lamp offers a high intensity, narrowband source of UV radiation. The wavelength of the light is chosen such that only the carbon aerosols.
