High Sensitivity

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.

Detection Sensitivity 100x Higher than TCD, 2x Higher than FID

Novel Universal Detector

Single Detector Approach for Your Complex Analyses

Long-Term Stability

Long-Term Stability with New Discharge Design

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.
