Olfactory Detection Port ODP

Parallel olfactory detection of GC fractions.

The ODP sniff port allows the sensing of compounds by the human nose as they elute from the gas chromatograph. The effluent is split as it leaves the column so that it arrives simultaneously at the nose and at the detector.

This way additional information is gained on compounds that are responsible for specific odors.

 

GERSTEL ODP offers:
  • Parallel operation with most standard detectors, including MSD
  • Humidifier for convenient usage
  • Voice recording and voice recognition: Spoken comments are transferred and added automatically to the chromatogram as peak annotations
  • ODP 3 provides a heated mixing chamber in which humidified make-up gas and column effluent are mixed without risk of condensation

NEW: Olfactory Data Interpreter (ODI) Software

The Olfactory Data Interpreter (ODI) software enables time-aligned sensory evaluation of compounds eluting from the GC/MS complete with intensity levels and qualifiers displayed in a combined olfactogram. Compounds can be searched in the NIST database and their identity added and reported.
The ODI software provides the analyst with helpful software tools that are also relevant for evaluation of sensory panel data such as: Cumulative Olfactogram presentation, Aroma Extract Dilution Analysis (AEDA), Flavor Dilution (FD), as well as Multivariate Data Analysis (PCA).
