Multi Residue Analysis of Pesticides by GC-HRMS

You're invited to publicize your 2024–2025 new product introductions in LCGC. Here's how to get your products included.

In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.

A study aiming to identify fluorescent bioactive compounds in the coelomic fluid of earthworms, as well as to investigate their structural and functional characteristics for possible use in biomedical applications, utilized a variety of chromatographic techniques.

Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.

This study analyzes total fluorine and chlorine in food packaging using combustion ion chromatography, ensuring consumer safety amid PFAS restrictions and regulations.

University of Turin scientists developed a UHPLC–PDA-MS/MS-based method for quantifying plant-specialized metabolites for determining the quality of medicinal and aromatic plants.
