Decoding Odors - Detection and Identification
Webinar 1 of 3 | August 21, 2025
Discover how the human sense of smell can add value to your chromatographic and mass spectrometric results.
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) method.
This covers i.e. the following application areas:
• Food & Beverage
• Flavor & Fragrances
• Material Emissions
• Environmental
• Medical & Life Science
This webinar introduces the GERSTEL ODP and all its special features as well as the ODI software, which you can use to identify the scents detected. Join this engaging webinar to experience:
• Real-world applications
• Expert tips for avoiding common pitfalls
• Software demonstration
If you're curious about how to make odor perception measurable and visible, this webinar is the place to start.

Uncovering the Cause – Identifying Off-Odors with Sensory Directed Analysis
Webinar 2 of 3 | August 26, 2025
Discover how to make the invisible - but smellable - detectable!
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.
Therefore, secure your spot now!

From Aroma to Insights – Identifying Key Sensory-Active Compounds
Webinar 3 of 3 | August 27, 2025
Discover how to reveal the aromatic secrets of complex samples!
In this engaging Webinar, Nicole Kfoury (Application Scientist, GERSTEL Inc., USA) demonstrates how Sensory Directed Analysis (SDA) reveals the key compounds behind complex aromas – using real-world examples from bourbon and perfume.
In addition, the webinar will showcase two powerful techniques that can be seamlessly integrated with GERSTEL ODP 4 and Olfactory Data Interpreter (ODI) software:
• Aroma Dilution Analysis (ADA)
• Frequency Detection (e.g. Nasal Impact Frequency; NIF)
You’ll learn how to identify the most impactful odor-active compounds by combining mass spectrometry and the human nose – even when compounds are below the detection limits of analytical instruments.
The webinar also covers advanced techniques like:
• Multi-Desorption Mode
• Sniff & Trap Function
• Selectable 1D/2D-GC
Whether you’re working with spirits, fragrances, or any aroma-rich product, this webinar offers practical tools to elevate your sensory analysis strategy.
