The Tracera system is based on the GC-2010Plus gas chromatograph, equipped with a unique highly sensitive Barrier Discharge Ionization Detector (BID). It allows the detection of trace amounts of compounds of various nature that are difficult or impossible to detect using standard chromatographic detectors.
Tracera GC-2010Plus-BID
Chromatographic system
Features
- High sensitivity. BID achieves a detection limit that is 50-100 times better than TCD and, depending on the substance, 1.5-5 times better than FID.
- Universality. Samples containing a large number of compounds of different nature can be analyzed using a single universal detector.
- Work stability. Despite its high sensitivity, BID is very resistant to high concentrations of analyzed samples.
Barrier discharge ionization detector BID-2010Plus. Shimadzu discovers a new principle in helium ionization technology and offers a state-of-the-art barrier discharge ionization detector (BID). Thanks to its combination of long-term stability and high sensitivity, the BID fills a previously existing gap in the detector line and occupies a place between the reliable but low-sensitivity thermal conductivity detector and the highly sensitive but rather difficult-to-use pulsed discharge helium ionization detector (PDHID). As in most helium ionization detectors, helium plasma is formed by electrically exciting helium atoms. The discharge gas (ultrapure helium), which is used for this purpose, is supplied to the detector head. Electrodes made of sapphire-cobalt alloy transfer helium to an excited state and create a cold helium plasma. Ionization of substances occurs under the influence of light emitted by the helium plasma (energy 17.7 eV). The BID detector was developed in collaboration with Dr. Katsushyo Kitano from the Center for Atomic and Molecular Technology, Osaka University.
