The study of the thermal behavior and pyrolysis products of these terpenoids could possibly suggest flavor precursors that could be used to provide specific flavors.

Py-GC–MS Investigation of Pyrolysis Behaviors and Decomposition Products of α- and β-2,7,11-cembratriene-4,6-diols

Elinor Hughes obtained her B.Sc. in chemistry and Ph.D. in organic chemistry at Bangor University, UK. After working for a chemical manufacturing company for three years, she moved to the Royal Society of Chemistry where she worked in journals publishing for six years and on Chemistry World magazine for four years. This was followed by five years as a freelance copyeditor and science writer. Her current role is technical copywriter at Markes International.

This study demonstrates the analysis of live chemical warfare agents and simulants at trace and higher levels.

How Tube-Based Thermal Desorption Can be Used to Monitor Chemical Warfare Agents at Ultratrace Levels

Tony Taylor is Group Technical Director of Crawford Scientific Group and CHROMacademy. His background is in pharmaceutical R&D and polymer chemistry, but he has spent the past 20 years in training and consulting, working with Crawford Scientific Group clients to ensure they attain the very best analytical science possible. He has trained and consulted with thousands of analytical chemists globally and is passionate about professional development in separation science, developing CHROMacademy as a means to provide high-quality online education to analytical chemists. His current research interests include HPLC column selectivity codification, advanced automated sample preparation, and LCâMS and GCâMS for materials characterization, especially in the field of extractables and leachables analysis.

Understanding the design and operation of a quadrupole mass analyzer can help you plan, optimize, and troubleshoot analytical methods.

The Beauty of the Quadrupole Mass Analyzer

Analysis of polyaromatic hydrocarbons (PAHs) in air demonstrates that a TD–GC–MS system can operate with hydrogen carrier gas as well as it does with helium.

How Switching from Helium to Hydrogen Carrier Gas in Thermal Desorbers Enhances Gas Chromatography–Mass Spectrometry Systems

QuEChERS has been updated to suit modern instrumentation. Now also “efficient and robust,” QuEChERSER is a “mega-method” that covers a wider polarity range.

The QuEChERSER Mega-Method

This novel gas chromatography (GC)–MS approach enables analysis of the suspected mutagens bis(pinacolato)diboron (BPD) and tetrahydroxydiboron (BBA) found at low-levels in certain intermediates and active pharmaceutical ingredients (APIs), even in the presence of boron from other sources.

Analysis of Boronic Compounds as Potential Mutagenic Impurities in Drug Substances By GC–MS 

In this month’s blog, we provide information about the Subdivision on Chromatography and Separations Chemistry (SCSC) of the Analytical Division of the American Chemical Society (ACS), sharing our main goals and introducing our newly appointed executive board members.

This study illustrates the importance of column selection during GC method development.

Profiling Free Naphthenic Acids in Produced Water Using Gas Chromatography Coupled to High-Resolution Accurate Mass–Mass Spectrometry (GC–HRAM-MS)

In 2015, the American Chemical Society’s Committee on Professional Training added a requirement to the ACS degree certification program that undergraduates learn about macromolecules, supramolecular aggregates, and nanomaterials (MSN). This requirement can be met by a specialized course in these topics, but many programs are also choosing the distribute these topics across the curriculum.
