    POWTECH 2004: Dekati Ltd.

    Stand 11-302

    Dekati Ltd. will be presenting a range of particle measurement instruments in Partec 2004. Dekati’s product line includes both novel real-time instruments for particle mass and number concentration measurement, as well as instruments based of gravimetrical method.

    ELPI(TM) (Electrical Low Pressure Impactor) enables real time particle size distribution and concentration measurement in the size range from 7 nm up to 10 um. ELPI is intended for any application where a wide size range coverage and fast time response are required. Such applications include combustion aerosol studies, filter testing and general aerosol research.

    ELPI operating principle combines the accuracy of impactor size classification and rapid electrical detection in the same device. With ELPI it is possible to measure transient particle size distributions in a wide range of particle sizes and concentrations. After the real-time measurement, chemical analysis of the size classified, collected particles can be performed.

    ELPI operating principle:
    The gas sample containing the particles is first sampled through a unipolar corona charger where a precisely know charge is given to them. The charged particles then pass into a low-pressure impactor with electrically isolated collection stages. The electric current carried by charged particles into each impactor stage is measured in real time by a sensitive multichannel electrometer. The components are housed in a single compact unit. A standard RS232 port is provided for communication with a laptop or PC computer.
