    EcoChem - Model PAS 2000CE - Compact Real-Time Photoelectric Aerosol Sensor

    The PAS 2000 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 are ionized, while gas molecules and non-carbon aerosols remain neutral. The carbon aerosol particles emit electrons, which are subsequently removed when an electric field is applied. The...
