1. A portable system for the spectroscopic analysis of aerosol particles, the system comprising:

  • an aerosol collection device further comprising;

    a housing defining an inlet and an outlet;

    a corona electrode disposed proximally to the inlet; and

    ,a ground electrode disposed proximally to the outlet;

    wherein the ground electrode is aligned coaxially with the corona electrode and is separated from the corona electrode by a gap;

    a high voltage source in communication with the corona electrode;

    a radio frequency power supply in communication with the corona electrode;

    wherein the corona electrode is held at a bias voltage provided by the high voltage source;

    wherein a glow discharge is generated at the corona electrode by the radio frequency power supply; and

    , wherein the glow discharge ablates aerosol particles collected on ground electrode.
