Metrohm Measures Ions in Alcoholic Beverages
Metrohm UK (Buckingham, UK) has developed a method for analyzing samples of beer and intermediates for anions and cations ? alkali and alkaline earth metals ? using ion chromatography and voltammetry.
Metrohm UK (Buckingham, UK) has developed a method for analyzing samples of beer and intermediates for anions and cations — alkali and alkaline earth metals — using ion chromatography and voltammetry. Ion chromatography is used in the brewing industry to monitor anion profiles in the quality control process. The anions in beer largely consist of impurities from the water used during the brewing process. They can affect the flavor of the final product and must be carefully monitored. The company’s IC systems can be used to analyze vodka samples without any sample preparation, and results reportedly are available in less than 10 min. Voltammetry is used to check for the presence of trace levels of metal impurities.
LC–MS/MS-Based System Used to Profile Ceramide Reactions to Diseases
April 26th 2024Scientists from the University of Córdoba in Córdoba, Spain recently used liquid chromatography–tandem mass spectrometry (LC–MS/MS) to comprehensively profile human ceramides to determine their reactions to diseases.
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.
