Abstract: A spark-induced breakdown spectroscopy apparatus can have a housing with an inlet and an outlet that define an analyte flow path. A laser can define a laser pathway generally transverse to an intersecting the analyte flow path. A pair of electrodes, which can have insulating shields, can be mounted within the housing and can define a spark path. An optical detection element defines an optical path. The apparatus can be used to identify an aerosolized analyte.
