Identifying and Rectifying the Misuse of Retention Indices in GC
December 10th 2024LCGC International spoke to Phil Marriott and Humberto Bizzo about a recent paper they published identifying the incorrect use of retention indices in gas chromatography and how this problem can be rectified in practice.
Overcoming Common Challenges to Determine Residual Impurities Using IC in APIs with Limited Water
December 10th 2024Organic solvents are generally not compatible with ion chromatography (IC) systems. The approach presented here assists the use of organic solvents for sample preparation and provides a mechanism for the removal of the organic solvents from the chromatographic flow path.
Investigating the Influence of Packaging on the Volatile Profile of Oats
December 10th 2024In the testing of six different oat brands, headspace sorptive extraction and comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC–TOF-MS) reveal how various packaging types can affect and alter the oats’ volatile profile, underscoring the potential impact of packaging on food quality.
ID-LC–MS/MS Used to Determine Associations Between PUFA and Estradiol Levels
A recent study investigating the association between dietary polyunsaturated fatty acid (PUFA) intake and estradiol levels in women in the United States utilized isotope dilution liquid chromatography–tandem mass spectrometry to measure serum estradiol levels.
SPME GC-MS–Based Metabolomics to Determine Metabolite Profiles of Coffee
Using a solid phase microextraction gas chromatography-mass spectrometry (SPME GC-MS)-based metabolomics approach, a recent study by the School of Life Sciences and Technology at Institut Teknologi Bandung (Indonesia) investigated the impact of environmental factors (including temperature, rainfall, and altitude) on volatile metabolite profiles of Robusta green coffee beans from West Java.
Mass Spectrometry Analysis Sheds Light on Mysterious Marine Debris
LCGC International sat down with Christopher Kozak, a professor at Memorial University to speak about his recent research using MALDI-TOF analysis to identify unknown blobs in Newfoundland, Canada’s Placentia Bay.
