Fast and Accurate GC–MS Analysis of Polycyclic Aromatic Hydrocarbon (PAHs) in Rubber and Plastic Using a Zebron™ ZB-PAH-EU GC Column

In this edition of the LCGC Blog, Amber Hupp of the College of the Holy Cross reflects on her childhood and talks about her journey recreating the scents from that long past.

Microplastics and nanoplastics have been identified in the lungs of wild birds using laser direct infrared (LDIR) chemical imaging and pyrolysis gas chromatography–mass spectrometry (Py-GC–MS), in the first multi-species evidence of these plastics in bird lungs.

Not all chromatography resins are created equal. Off-the-shelf chromatography resins might not always meet the rigorous purification requirements of biopharmaceutical manufacturing. Custom bonded silica from Grace can address a wide range of separation challenges, leading to real performance improvements. Discover more about the latest innovations in chromatography silica from Grace, including VYDAC® and DAVISIL®.

Particularly in the pharmaceutical industry, drug purity isn’t just a goal – it’s essential for achieving safety, stability and efficacy. However, purification is easier said than done, especially with challenging molecules like DNA and RNA “oligonucleotides,” due in large part to their diversity and the range of impurities that can be generated during production. Enter DAVISIL® chromatographic silica, with a wide range of pore diameters and particle sizes to meet your specific application, performance and sustainability requirements. Before you choose the chromatography resin for your next purification application, take a look at these 5 considerations.

Iowa State University researchers evaluated imidazolium-based ZILs with sulfonate and triflimide anions to understand the influence of ZILs’ chemical structures on polar analyte separation.
