TraceraHigh sensitivity gas chromatography system

Traditional gas chromatography detectors are difficult to handle the analysis of trace substances in gases. Shimadzu Corporation has developed a new high-sensitivity gas chromatography system called Tracera, which integrates capillary type detectorsgas chromatographThe carefully designed BID detector (dielectric barrier discharge plasma detector) technology of GC-2010 Plus demonstrates strong analytical advantages in this regard, fully meeting the needs of trace substance analysis

high sensitivity

More than 100 times more sensitive than TCD and more than 2 times more sensitive than FID

High Universality

A single detector fully meets the requirements of complex analysis

high stability

Dielectric barrier discharge plasma generation technology ensures long-term stability of instruments

New plasma technology meets the requirements of trace analysis

The new BID detector (dielectric barrier discharge plasma detector) mainly ionizes helium plasma generated by dielectric barrier discharge, and is a highly sensitive universal detector. At lower temperatures, a helium plasma with extremely high photon energy (17.7eV) is generated by applying a high voltage to a quartz glass tube.

The components flowing out of the chromatographic column are ionized under the energy bombardment of helium plasma, and the ion signal is detected by the collecting electrode to output the chromatographic peak.

The BID detector is a collaborative research result between Shimadzu Corporation and Dr. Katsuhisa Kitano from the Atomic and Molecular Technology Center of the Graduate School of Engineering at Osaka University in Japan. Currently, it has obtained 3 US patents and 4 patents pending approval.
