Profiling Volatile Organic Compounds in Whisky with GC×GC–MS
November 1st 2024Researchers from Austria, Greece, and Italy conducted a study to analyze volatile organic compounds (VOCs) present in Irish and Scotch whiskys using solid-phase microextraction (SPME) Arrow with comprehensive two-dimensional gas chromatography coupled to mass spectrometry (GC×GC–MS) to examine the organoleptic characteristics that influence the taste of spirits.
GC–TOF-MS Finds 250 Volatile Compounds in E-Cigarette Liquids
November 1st 2024A study has used gas chromatography coupled to a time-of-flight mass spectrometer to build an electron ionization mass spectra database of more than 250 chemicals classified as either volatile or semi-volatile compounds. An additional, confirmatory layer of liquid chromatography–mass spectrometry analysis was subsequently performed.
GC–MS Targeted Analysis of PFAS Helps Expand Knowledge of Toxicokinetic Data
November 1st 2024Limited toxicokinetic and toxicologic information is available about a diverse set of per- and polyfluoroalkyl substances (PFAS), but methods based on gas chromatography–tandem mass spectrometry (GC–MS/MS) can help unravel some of the mystery.
Identifying PFAS in Soil Samples
October 17th 2024Jonathan Zweigle of the University Tübingen spoke with LCGC International about his work using non-targeted screening based on high-resolution mass spectrometry (HRMS) to detect PFAS in soil samples. HRMS allows scientists to determine the elemental and isotopic composition of a sample with high accuracy.
Inside the Laboratory: Grinias Research Lab at Rowan University, Part IV – Advice from Students
July 8th 2024In this continuing series from LCGC, we go on location to the Grinias Research Lab at Rowan University, where graduate students gave advice for up and coming separation scientists following in their footsteps.
Technology Trends in Separation Science: Data Handling
Published: July 3rd 2024 | Updated: July 8th 2024LCGC International spoke with Shawn Anderson, Associate Vice President of Digital Lab Innovations at Agilent Technologies; Marco Kleine, Head of the Informatics Department at Shimadzu Europa GmbH; Trish Meek, Senior Director, Connected Science, Waters Corporation and Todor Petrov, Senior Director, QA/QC, Waters Corporation; and Crystal Welch, Product Marketing Manager at Thermo Fisher Scientific about the latest trends in data handling.
PLS-DA With Univariate Filtration Refines Discovery of Untargeted Metabolomics Data Using LC–MS
June 3rd 2024As opposed to targeted metabolomics which looks only at a predetermined set of metabolites or their pathways, an untargeted approach was preferred by this research team because of its unbiased yet still comprehensive nature.
TD-GC–MS and IDMS Sample Prep for CRM to Quantify Decabromodiphenyl Ether in Polystyrene Matrix
April 26th 2024At issue in this study was the certified value of decabromodiphenyl ether (BDE 209) in a polystyrene matrix CRM relative to its regulated value in the EU Restriction of Hazardous Substances Directive.
High-Throughput 4D TIMS Method Accelerates Lipidomics Analysis
April 25th 2024Ultrahigh-pressure liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) had been previously proposed for untargeted lipidomics analysis, but this updated approach was reported by the authors to reduce run time to 4 min.
Thermo Fisher PFAS Expert Discusses Laboratory Testing, Regulatory Partnerships
April 22nd 2024On this Earth Day, LCGC sits down with Toby Astill of Thermo Fisher Scientific to talk about laboratory testing of PFAS and how companies and industry work in tandem with governments and regulatory agencies to share information and effect changes in standards.
Lipidomics Advances and Females in Mass Spec: An Analytica Interview with Anne Bendt
April 12th 2024Bendt, of SLING, or Singapore Lipidomics Incubator, spoke with LCGC at Analytica 2024 about her research in the field of lipidomics, and about her work laying the ground for the Females in Mass Spectrometry group.
