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.

The BID was developed thru collaborative research with Dr. Katsuhisa Kitano, Center for Atomic and Molecular Technologies, Graduate School of Engineering, Osaka University, resulting in 3 U.S. patents and 4 patents pending.
