LC–MS Methods Evaluate PFAS and Lipidomic Changes of Lettuce and Peanuts in Contaminated Soil
June 6th 2023In a talk at ASMS 2023, Rebecca L. Beres of the University of North Carolina at Chapel Hill focused on two types of analysis methods: liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) and a liquid chromatography, ion mobility spectrometry, and mass spectrometry (LC–IMS-MS) platform.
ASMS 2023 Will Host its Closing Event at the Houston Museum of Natural Science
May 26th 2023ASMS will conclude its conference at the Houston Museum of Natural Science (HMNS) on Thursday June 8th, from 7:00 to 10:00 pm. The HMNS is known for their paleontology display, giving attendees the opportunity to embark on a one-of-a-kind prehistoric journey while socializing with friends and colleagues.
An Interview with AI About Its Potential Role in Separation Science
May 17th 2023We interviewed an AI program (ChatGPT) for LCGC North America asking questions about AI and its role in various applications for separation science to include data analysis, and high performance liquid chromatography (HPLC), hydrophilic-interaction chromatography (HILIC), reversed-phase liquid chromatography (RPLC), liquid chromatography–mass spectrometry (LC–MS), gas chromatography–mass spectrometry (GC–MS), high resolution mass spectrometry (HRIM–MS), high resolution tandem mass spectrometry (HRMS/MS), and related topics.
New Analytical Tool Helps Probe Higher-Order Structure of Bispecific Antibody Therapeutics
April 24th 2023The development of a new tool that combines native ion mobility-mass spectrometry (IM-MS) and collision-induced unfolding (CIU) could lead to a better understanding of bsAbs and aid in the development of effective treatments for diseases that remain challenging for conventional mAb therapeutics to access.
Carol V. Robinson Wins 2023 John B. Fenn Award for Distinguished Contribution in Mass Spectrometry
April 24th 2023Carol V. Robinson of the University of Oxford has been named the 2023 recipient of the ASMS John B. Fenn Award for Distinguished Contribution in Mass Spectrometry. Robinson will receive the award at the 2023 ASMS Conference in Houston, Texas, which takes place June 4–8.
New Ultrasonic Spray Ionization Method Improves Mass Spectrometry Analysis
April 21st 2023A new method was recently developed that has the potential to revolutionize the use of piezoelectric atomizers in MS analysis, and ultimately provide a more efficient and superior soft ionization approach for the direct analysis of a variety of samples, including aqueous solutions.
New Method Developed to Detect N-Nitrosamines in Pharmaceuticals
April 19th 2023Sartans are important drugs that help treat hypertension and heart failure. However, since their recall in 2018 because of the presence of genotoxic impurities in these drugs, researchers are tackling the question of how to detect these impurities in these drugs before they go to market. This article describes a HPLC–APCI-MS/MS method that can help in this endeavor.
