The present invention provides an ionization detector having a base having an enclosed chamber. The enclosed chamber has a first end and a second end. The detector also includes a first outlet which is a source of an excitable medium. A second outlet is provided which functions a source of an analyte that is transported by a carrier gas. An ionization source for creating a discharge from said excitable medium is also provided. The collector electrode generates a time dependent current based on its interaction with ionized analytes from which the analyte may be detected.
