GERSTEL Headspace ChemSensor System

GERSTEL Headspace ChemSensor System

Unlike traditional electronic noses that are based on solid-state sensors, the GERSTEL ChemSensor System use proven quadrupole mass-spectrometer technology.

Benefits:
  • The GERSTEL Headspace ChemSensor System is unaffected by moisture in the sample, ambient humidity, or ambient temperature fluctuations. It is also immune to sensor poisoning.
  • Quadrupole technology enables customized screening and classification for multiple applications on the same system.
  • The GERSTEL Headspace ChemSensor System can ignore ions associated with dominant sample components – such as alcohol in wines or acetic acid in salad dressings – and model only the critical factors that differentiate samples.
  • Ions in a suspect sample that are not present in a good sample can be monitored in subsequent analyses using GC/MS. This can reduce troubleshooting time substantially and puts you steps ahead of e-noses that do not have this correlation capability.

MAESTRO Software

MAESTRO Software

Introduction Perfectly Synchronized

The MAESTRO software operates all GERSTEL modules and system solutions in a simple and efficient manner. MAESTRO can be operated as stand-alone software or fully integrated with the Agilent Technologies ChemStation. Just one method and one sequence table runs the complete system from Sample Prep and Sample Introduction to GC/MS or LC/MS analysis. Set-up is performed in a very simple manner: By mouse-click.

Olfactory Data Interpreter (ODI)

Olfactory Data Interpreter (ODI)

GERSTEL Enterprise Edition powered by OpenChrom

The GERSTEL Olfactory Data Interpreter (ODI) enables fast and reliable evaluation of olfactory information including identification of unknown odor-active compounds. Chromatography data is typically acquired using a mass spectrometer / mass selective detector (MSD), a Flame Ionization Detector (FID) or a Sulfur Chemiluminescence Dectector (SCD) or a combination thereof. The chromatogram is loaded into the ODI software, which automatically recognizes the chromatogram data format before importing the data. In parallel, an olfactogram is imported with information provided by the user as he or she assessed odors eluting from the GC column in parallel with the detection process during the GC run. The olfactogram combines spoken comments from the sensory analyst and the registered intensities along a time axis. The „Olfactory Intensity Device“ (OID) conveniently enables the user to indicate the intensity of the olfactory impression as it transpires. Text comments are added using voice recognition software to translate spoken descriptors. The combined information is presented in the ODI-Software in a clear and concise overview including a chromatogram, an olfactogram and a table.
