Characterizing Cooked Cheese Flavor with Gas Chromatography
A joint study by the Department of Food and Nutritional Sciences at the University of Reading and Synergy Flavours aimed to identify volatiles that contribute to the aroma of cooked cheese, including the role of fat content in development during cooking.
Deep Learning Framework for Peak Detection at the Intact Level of Therapeutic Proteins
Although automated peak detection functionalities are available in commercially accessible software, utilizing visual inspection and manual adjustments to achieve optimal true positive rates is often necessary. A recent study conducted by the Department of Chemical Engineering at the Indian Institute of Technology (Delhi, India) used liquid chromatography-mass spectrometry (LC–MS) to distinguish hetero-variants (glycoforms) resulting in a monoclonal antibody (mAb) able to be characterized, revealing discernible peaks at the intact level. LCGC International spoke to Anurag Rathore, corresponding author for the article, about his department’s findings.
Using GC-MS to Investigate the Aroma Composition of Cheese
Researchers from the Department of Bioscience and Technology for Food, Agriculture and Environment at the University of Teramo (Italy) used gas chromatography-mass spectrometry (GC-MS) investigated the contribution of Kluyveromyces marxianus to the gross composition and aroma profile of cow cheeses.
New Algorithm Created for Detecting Volatile Organic Compounds in Air
October 9th 2024Scientists from Institut de Combustion, Aérothermique, Réactivité et Environnement (ICARE-CNRS) in Orléans, France and Chromatotec in Saint-Antoine, France recently created a new algorithm for detecting volatile organic compounds (VOCs) in ambient air.
Using GC–MS to Track Effects of Second-Hand Cigarette Smoke in Nightclub Attendees
A pilot study conducted by the University of Split School of Medicine (Split, Croatia) used gas chromatography-mass spectrometry (GC–MS) to measure the urine levels of nicotine and its metabolites in research participants exposed to second-hand smoke in nightclubs.
Green Chemistry Highlighted During International Symposium on Chromatography
October 8th 2024Regarded as one of the pioneers of the green chemistry movement, John Warner took the stage at the ISC in Liverpool to speak about the pivotal role separation scientists must play in advancing green chemistry.
ISC 2024: An Interview with Amarande Murisier
October 8th 2024As part of our ISC 2024 coverage, we recently interviewed Amarande Murisier of the University Hospital of Lausanne, Switzerland (CHUV) about her winning the Rising Stars of Separation Science Award for Biopharmaceutcal Analysis and her scientific background.
Metabolomic Study of Patients with Wet Age-Related Macular Degeneration in Aqueous Humor
A recent study ascertained metabolic biomarkers and investigated the metabolic alterations associated with aqueous humor (AH) in wet age-related macular degeneration (AMD). Analysis was performed using liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify and quantify metabolites.
