SDA Webinar Series

Let Your Nose be Your Guide

Discover how the human sense of smell can add value to your chromatographic and mass spectrometric results.


Discover how to make the invisible - but smellable - detectable!

Webinar No 2:
Uncovering the Cause - Identifying Off-Odors with Sensory Directed Analysis.


In this webinar, Nicole Kfoury (Application Scientist, GERSTEL Inc., USA) introduces the GERSTEL Olfactory Detection Port (ODP 4) and the powerful Olfactory Data Interpreter (ODI) software, which can be used to detect and identify scents using the GERSTEL Sensory Directed Analysis (SDA

In this Webinar, Nicole Kfoury (Application Scientist, GERSTEL Inc., USA) demonstrates how Sensory Directed Analysis (SDA) can be used to pinpoint even the faintest off-odors in complex samples.


SDA enables the detection of odor-active compounds that may otherwise remain hidden from traditional analysis – from packaging materials to fermented beverages - by combining:

• Gas Chromatography

• Mass Spectrometry

• Human Nose


Through two real-world case studies, you learn how to apply SDA to isolate and identify problematic compounds, even at trace levels. The webinar covers:

• Thin-Film SPME & Twister, for high-capacity extraction

• Multi-Desorption Mode, to boost sensitivity

• Selectable 1D/2D-GC, for enhanced separation


Whether you're facing customer complaints or seeking to ensure product quality, this webinar provides practical strategies and insights that make the invisible finally detectable.
