Plasma Technology for Universal Trace Analysis  The barrier discharge ionization detector (BID) is a highly sensitive device that creates ionization from a Helium-based, dielectric barrier discharge plasma. A 17.7eV plasma is generated by applying a high voltage to a quartz dielectric chamber, in the presence of helium at a relatively low temperature.  Compounds that elute from the GC column are ionized by this He plasma energy and then detected by the collection electrode and processed as peaks.
