“Tracera”, High-Sensitivity Gas Chromatograph System
The Tracera includes Shimadzu's new Barrier Discharge Ionization Detector (BID-2010 Plus) mounted on the GC-2010 Plus High-Performance Capillary Gas Chromatograph. The BID-2010 Plus uses an ionization method using helium plasma so it offers highly sensitive detection of all compounds except the carrier gases helium (He) and neon (Ne). The detector offers over 100 times higher detection sensitivity than TCDs and can detect compounds such as aldehydes and alcohols, for which FIDs tend to achieve a low sensitivity. Therefore, it can be used for applications for trace impurity analysis on gas and liquid samples that TCDs or FIDs could not support.


Principles of Barrier Discharge Ionization Detector (BID)
The barrier discharge ionization detector (BID) is a detector that uses ionization by dielectric barrier discharge plasma. It offers highly sensitive detection of all compounds except the carrier gases helium and neon. Its sensitivity is approximately 1.5 times higher than that of FIDs and over 100 times higher than that of TCDs, so that it allows ppm-order compound analysis.
One of the features of the BID is dielectric barrier discharge, where plasma is generated using a low-frequency power source from the outside of the dielectric substance (quartz). Compounds that elute from the column are ionized by light energy from the He plasma and then collected by the
collection electrode, which outputs them as peaks.
