Shimadzu's High-Sensitivity Gas Chromatograph Incorporates Novel Plasma Technology to Enable Trace Analysis- Achieves detection sensitivity over 100 times that of general-purpose TCD, and over twice that of FID - 
The barrier discharge ionization detector (BID), that is collaboratively developed by Prof. Kitano/PARC and Shimadzu, 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.
