Several methods of determining moisture and ash content, with a focus on the weight loss on drying method for moisture and the weight loss after combustion method for ash.

Explore the differences between the Kjeldahl and Dumas methods and describe the benefits of the latter. We also cover the advantages of the ballast/aliquot principle, provide analytical examples, and conduct a live demonstration, followed by a Q&A session.

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.

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.

Water content in soil and plant tissue is an important parameter that can influence crop growth, yield, and quality. In addition, moisture plays an important role in commerce and storage of food products. Determination of ash in soil can be used to approximate the organic content of the soil.

Utilizing Gas Chromatography-Olfactometry (GC-O) can help identify active odor compounds in complex mixtures. But, what happens if GC-O does not identify a compound, but an off-flavor or malodor is still present?

Liz Humston-Fulmer [LECO] utilized GCxGC TOF-MS technologies to understand the chemical composition of CBD-infused beverages.

Liz Humston-Fulmer [LECO] discusses how GC-MS can isolate analyte differences among aging beer samples.

Liz Humston-Fulmer [LECO] discusses how the Pegasus BT (with L-PAL3 Autosampler) identifies analyte changes due to aging of commercially available IPA beer.

Ray Marsili [Marsili Consulting Group] discusses the use of chromatograms to determine flavor and fragrance anomalies within various samples.

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.
