The new Tracera GC System is now ready to solve your trace analysis needs. This system utilizes the new Barrier Discharge Ionization Detector technology coupled with a GC-2010 Plus capillary gas chromatograph to create a GC system that makes it possible to reveal trace components that are difficult to see by other GC detectors.

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.
Comparison of Detectable Compounds
| Detector Type | Detectable Compounds |
| Barrier discharge ionization detector (BID) | All, except He and Ne |
| Thermal conductivity detector (TCD) | All, except carrier gas |
| Flame ionization detector (FID) | Organic compounds, except formaldehyde and formic acid |
