GC SNFR Olfactory Port

Importance of Aroma Characterization

Aroma profiling plays a critical role in food, beverage and fragrance industries by linking sensory perception to chemical composition. Accurate evaluation of volatile compounds ensures consistent product quality, guides flavor development, and supports regulatory compliance.

Study Goals and Overview

This application note introduces the PerkinElmer GC SNFR Olfactory Port, designed to integrate human sensory evaluation directly with gas chromatography and GC/MS analysis. The primary objectives are to maintain precise retention time alignment, capture real-time odor impressions, and overlay sensory data on chromatograms for comprehensive sample profiling.

Methodology and Instrumentation

The system splits the flow from a capillary GC column between the MS detector, up to two additional detectors, and the SNFR Olfactory Port without delay. Key features include adjustable, interchangeable nosepieces with humidified air control, an inert flow path, and built-in speech-to-text software. Users employ a simple joystick to record odor intensity and verbal notes, which are time-stamped and graphically superimposed on chromatograms.
