    • A gas particle partitioner (10) removes particles from an aerosol (28) with high efficiency and with no or minimum changes to the thermodynamic conditions and chemical composition of the gas phase of the aerosol. A permeable grid electrode (24) surrounds a corona wire (32) and separates an interior corona discharge area (34) from an exterior aerosol charging zone (30). A particle free fluid (42) washes the corona discharge area to minimize any transport of gas components produced by corona discharge to the aerosol. The charged particles (44) in the aerosol are deflected by an electric field F in a fractionator (16) to selectively produce a particle free sample stream (46), which is then separated by a flow splitter (18) from the aerosol.
    • 气体分隔器(10)以高效率从气溶胶(28)中除去颗粒,并且气溶胶的气相的热力学条件和气相的化学组成没有或最小变化。 可渗透的栅电极(24)围绕电晕丝(32)并将内部电晕放电区域(34)与外部气溶胶充电区(30)分离。 无颗粒流体(42)洗涤电晕放电区域以最小化由电晕放电产生的气体成分对气溶胶的任何运输。 气溶胶中的带电粒子(44)通过分馏器(16)中的电场F偏转,以选择性地产生无颗粒的样品流(46),然后由气流分离器(18)分离。
