Gas chromatography-mass spectrometry/pulsed-flame photometric detection-2ways-olfactometry system for simultaneous work with two sensory judges

Identification of Facility
TitleGas chromatography-mass spectrometry/pulsed-flame photometric detection-2ways-olfactometry system for simultaneous work with two sensory judges
AcronymGC-MS/PFPD-2W-Olfactometry-Agroscope Institute of Food Sciences
Key wordsGas chromatography, olfactometry, sulphur specific detection
ManufacturerAgilent Technologies
ModelGas chromatograph Agilent 6890 with mass spectrometer N5973 and O.I. Analytical PFPD model 5380 and two olfactometry stations
DescriptionGas chromatography-olfactometry allows to determine the odorant chemical constituents of a sample and, depending on the employed methodology, to obtain information on their individual odour impact on the sample’s overall odour. The combination with mass spectrometry gives access to structural identification, and the use of sulphur-specific detection such as the pulsed-flame photometric detector allows to detect volatile sulphur-containing compounds. The latter are often present in trace quantities only and are not detected by the classical physical detectors such as a mass spectrometer, but due to their low odour detection threshold, can have a significant impact on the sample’s odour. The described setup is equipped with two olfactometry work stations so that two sensory judges can work simultaneously on the same sample and a panel of about 20 trained judges is available. An automatic sampler type Gerstel MPS with liquid, S-HS and SPME-injection mode is also available.

Possibilities and limitsThe use of this infrastructure by external visitors strongly depends on the visitor’s experience in analytical chemistry/flavour analytics and experience with this type of equipment and data processing. The availability of staff and trained judges are crucial factors which need to be discussed in advance.
CertificationThe flavour analytics laboratory and the entire institute are certified according to ISO 9001:2008. Certification was confirmed in 2012 and is regularly renewed. Many of the institute’s laboratories are also accredited according to ISO 17025.

Application
Application fields Odour analysis, analysis of volatile odorant compounds, off-flavours
Application examples The present setup is regularly used to establish odour profiles of milk and meat products in order to differentiate samples based on their odorant constituents, determine the odorant compounds showing a strong influence on the sample’s odour, to specifically search for target odour notes and compounds (e.g. for biotechnological flavour enhancement) or for unwanted odour notes (off-flavour).
