The GC-DTIMS 2030 combines the high selectivity of the chromatographic separation technique with the extraordinary sensitivity for the drift tube ion mobility spectrometry (DTIMS). Therefore, the GC-DTIMS-combination is a very powerful analytical tool for a wide range of applications with excellent sensitivities. Drift tube ion mobility spectrometry (DTIMS) is a gas detection technology that separates and identifies chemical ions based on their mobility under an electric field at atmospheric pressure. DTIMS can be used to detect and to identify volatiles in aqueous, solid and gaseous matrices.

Sample preparation and injection

There are a wide variety of sample preparation, extraction and processing techniques each with their own advantages and disadvantages. Due to the integrated well established split/splitless injector technology, known from the conventionally gas chromatography, the sample introduction can be made by direct injection via a syringe or by solid phase micro-extraction (SPME).

The SPME, for example, is a simple and effective adsorption/desorption sample preparation technique that eliminates the need for solvents or complicated apparatus for concentrating volatiles, semivolatiles or nonvolatiles compounds in liquid samples or headspace and is fully compatible with the GC-DTIMS system. SPME also reduces the sample preparation time up 70% and can be automated.

Examples of Applications

  • Environmental analyses of water samples (e.g. hydrocarbons, PAHs, poly chlorinated biphenyls, phenols, organophosphate pesticides, trace odors)
  • Headspace analysis of trace impurities in polymer and solid samples
  • Toxicology analyses: blood alcohol or drugs Indoor air quality (e.g. aldehydes, terpenes, ketones)
  • Flavor analyses of food products
  • Detection of toxic industrial compounds (e.g. BTEX)
  • Analysis of breath for medical diagnostic
  • Product quality control by detection of target compounds
  • Detection of wood preservatives like lindane, penta-chlorophenol
