Ion Mobility Spectrometer (IMS) Trace Detector For Benchtop Gas Chromatograph
The stand-alone IMS by G.A.S. mbH enables the use of the IMS technology in very demanding gas phase applications where high separation capabilities and/or sensitivity are needed. Compared to other detectors the IMS offers a second dimension of separation and by that full orthoganality so that co-eluting compounds can still be separated before they are detected at low-/sub ppb level. According to the laws of IMS which operates at atmospheric pressure ions are separated by their mass and structure. Therefore isomeric compounds can also be separated.
The applied tritium source with a low intensity lies below the exemption limit of the EU directive 96/29 EURATOM. The operation of the device can be in the positive mode to e.g. test for heteroatomic compounds while also performing with outstanding sensitivity in the negative mode for e.g. halogenated or sulphurous substances.
The device comes as ready-to-couple with softwares for setting of detector parameters same as drift gas flow. The provided transfer line is temperature-controlled to avoid 'cold spots'. With the oven exit on the right the GC-typical MSD (mass selective detector), located on the
left side, can still be used in parallel.
ADVANTAGES
• Sensitive: Detection limits in the low ppbv (µg/m3) range for VOCs with heteroatoms like ketones, aldehyds, alcohols, amines or halogenated and sulphurous compounds
• Selective due to specific analyte ion drift times (2 dimensional separation, full orthogonality)
• Flexible: Positive and negative ion generation
• High GC sampling frequency
• No licence for 3H source required
according to EU directive 96/29 EURATOM
• High reproducibility
• Operation with nitrogen or synthetic air
• Atmospheric Pressure Ionisation (API)
• Stand alone data aquisition software and software suite for 3D GC-IMS data analysis
• No need for a radiation protection officer
