Industrial Applications of GC×GC
Monday, 8:30 AM - 12:00 pm; Room W184D

This workshop session focuses on the use of comprehensive GC (GC×GC ) on solving real-world problems in industrialized settings. Nearly 20 years since its innovative first application by Liu and Phillips, there has been a plethora of successful GC×GC  uses in a wide variety of industries and markets. Hear from a panel of industry experts as they each highlight how this technology has solved authentic problems that were either not being addressed or only partially solved by other established techniques. Topics covered will include forensic arson cases, consumer products, petroleum processing, and defense.

Lab Gauntlet

Tuesday through Thursday, 10:00 AM - 2:00 PM | Exhibit Hall, Booth #3429

Find your Flavor: Interpreting HS-SPME-GCxGC-MS Data on Jelly Beans
Jelly beans have gotten very good at hiding disgusting (or delicious) flavors beneath innocent sugar shells. Do you dare trust the results obtained with LECO’s Pegasus 4D GCxGC-TOFMS with HS-SPME to determine which jelly beans are safe to eat? Use the provided chromatograms and flavor decoders to identify the jelly beans provided and put your guesses where your mouth is—literally—by tasting the ones you deem safe.


Nexus Theater Presentation

A Multi-Technique Approach to Developing Methodology for Moisture Determination in Cannabis
Tuesday, 2:00 PM

Moisture determination in plant material is typically done using thermal gravimetric analysis (TGA). The methodology used, specifically the temperature and analytical gas, are important criteria for obtaining an accurate moisture value. Moisture determination in cannabis is complicated due to the various volatile organic compounds (VOC’s); some of which evolve at temperatures typically used for moisture determination.

This presentation will outline a multi-technique approach for determining the proper temperature and analytical gas composition to provide the most accurate moisture value in cannabis. Prior to TGA analysis, a representative sample is analyzed on thermally controlled instrumentation that determines moisture directly via Infrared detection in either an oxidizing, or inert atmosphere; thus allowing separation of moisture from VOC’s. This allows the user to determine the temperature and atmosphere necessary to liberate moisture yet minimizing evolution of VOC’s. This information is then used to develop the proper methodology for TGA analysis specific to cannabis.

Networking Session

Hot Topics and Use of Multidimensional GC (GC×GC )
Thursday, 10:30 AM - 12:00 pm; Room W187B

This popular networking session is a great way for attendees to connect with other GC×GC  users who have similar interests and challenges.

The purpose of this networking session is to bring together analytical chemists from a variety areas to discuss GCxGC applications and the technology. In attendance will be users and experts in the various technologies to answer general questions, discuss advantages and share tips and tricks of the trade. "Bring your tough questions. No question will go unanswered!"
