Sniff & Trap using adsorbent tubes This function enables isolation and concentration of odor active compounds of interest within a defined retention time window without the need for complex column switching systems. Thermal desorption of the trapped compounds can subsequently be performed in the TDU 2 for further analysis. Sniff & Trap allows uncomplicated handling of two types of analytical procedures: Voice recognition Spoken sensory descriptors are recorded and documented using state-of-the-art voice recognition. Noise cancelling features help eliminate disruptive background noise in the laboratory. The analyst can fully concentrate on the olfactory perception avoiding potential errors. Olfactory Intensity Device (OID) Simultaneously with the olfactory assessment and description, the intensity of the impression is registered by the simply choosing one of four intensity levels on the ODI. A Collection of separated volatile compounds over a defined retenti- on time window and re-analysis of the trapped compounds on a GC column with orthogonal polarity (offline heartcutting) for separation of co-eluting compounds. B Concentration of compounds not found in the chromatogram, but detected in the ODP, over multiple GC runs. The compounds are subsequently determined in a separate GC run. Humidification To prevent mucus membrane irritation, the adjustable make-up gas can be humidified. Product demonstration Application example from food industry
