LC-HRMS Technology Used to Track Chemical Migration in Reusable Plastic Bottles
Aiming to develop a comprehensive strategy for evaluating the chemical migration from various reusable plastic bottles, researchers from the University of Copenhagen utilized vacuum evaporation concentration (VEC) enrichment combined with liquid chromatography (LC) high resolution mass spectrometry (HRMS) analysis to investigate a wide range of materials from different manufacturers to identify those with higher and lower chemical migration rates.
RAFA 2024 Highlights: Contemporary Food Contamination Analysis Using Chromatography
November 18th 2024A series of lectures focusing on emerging analytical techniques used to analyse food contamination took place on Wednesday 6 November 2024 at RAFA 2024 in Prague, Czech Republic. The session included new approaches for analysing per- and polyfluoroalkyl substances (PFAS), polychlorinated alkanes (PCAS), Mineral Oil Hydrocarbons (MOH), and short- and medium-chain chlorinated paraffins (SCCPs and MCCPs).
Analyzing Organic Acids in Fruit-Based Kombucha Analogues Using HPLC
A recent study evaluated the potential of fruit by-products from acerola, guava, and tamarind’s potential in producing fermented beverages, with their acid profiles determined by high performance liquid chromatography (HPLC).
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.
RP-HPLC Analysis of Polyphenols and Antioxidants in Dark Chocolate
A recent study set out to assess the significance of geographical and varietal factors in the content of alkaloids, phenolic compounds, and the antioxidant capacity of chocolate samples. Filtered extracts were analyzed by reversed-phase high-performance liquid chromatography (RP-HPLC) with ultraviolet (UV) and spectrophotometric methods to determine individual phenolics and overall indexes of antioxidant and flavonoid content.

Advancing Bladder Cancer Research with Mass Spectrometry: A FeMS Interview with Marta Relvas-Santos
November 12th 2024LCGC International interviewed FeMS Empowerment Award winner Marta Relvas-Santos on her use of mass spectrometry to identify potential biomarkers and therapies for bladder cancer. She also shared insights on her work with FeMS and advice for fellow scientists.
LC–MS/MS Quantification of Plasma Proteins in Elephant Seals to Advance Wildlife Conservation
Liquid chromatography and tandem mass spectrometry (LC–MS/MS) was used to show that repeated stress can cause delayed but sustained changes in blood plasma proteins associated with water conservation, immune responses, fat metabolism, insulin sensitivity, iron recycling, and hormone transport in elephant seals. Some of these changes may be novel markers of recent and chronic stress exposure in marine mammals.
