GC-MS Video

Joining us from William and Mary, Dr. Katelynn A. Perrault Uptmor, PI of the Nontargeted Separations Laboratory , present her work of screening samples using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GCXGC-TOFMS) in forensic applications as novel types of evidence appear. Dr. Perrault Uptmor highlights initial approaches to method development for new samples and show recent applications related to chemical profiling of deposited fingermarks, organic gunshot residue and decomposition odor. She also discusses the implications of GCXGC-TOFMS sample visualization in the context of expert testimony for communicating screening processes in forensic casework within the courtroom.

We explore the capabilities of LECO technology and the impact it is having on overcoming the challenges faced in the Aroma, Flavor, and Fragrance industry.

Dr. Heather Bean (Arizona State University) discusses using GCxGC-TOF MS to detect and phenotype infections directly from lung samples.

Helium is becoming an increasingly limited natural resource; using Hydrogen to achieve increased chromatographic throughput in GC applications is attractive. Both have advantages and disadvantages. LECO experts investigated the use of Hydrogen as a carrier gas for GC-TOF-MS analysis. Nick Jones, LECOs Global Application and Development Director (Separation Sciences) presents the method transfer approaches used, the technological benefits, and application examples in the presentation below.

With ever-increasing demands on your time, labor, and resources, optimizing your workflow is essential. Learn best approaches from GC-TOFMS experts to enhance your one- and two-dimensional gas chromatography applications (GC-MS and GCxGC-MS) in this webinar.

Small time savings throughout the workflow can add up to big savings. See aroma and flavor examples of how automated sample prep and elevated Time-of-Flight Mass Spectrometry (TOFMS) analysis, followed by software solutions to compare and evaluate data and results, can save your lab time and resources.
