A Question of Time (and Date)

University of Valladolid scientists used a miniaturized method for analyzing biogenic volatile organic compounds (BVOCs) emitted by tree species, using headspace solid-phase microextraction coupled with gas chromatography and quadrupole time-of-flight mass spectrometry (HS-SPME-GC–QTOF-MS) has been developed.

Karolinska University Hospital researchers recently tested new approaches for analyzing drugs of abuse in oral fluids.

A recent roundtable discussion featuring Aloka Srinivasan of Raaha, Mayank Bhanti of the United States Pharmacopeia (USP), and Amber Burch of Purisys discussed the challenges surrounding nitrosamine analysis in pharmaceuticals.

A team of researchers from Waters Corporation, led by Szabolcs Fekete, tested a new approach for separating oligonucleotides.

University of Caldas and University of Chile researchers extracted estrogenic hormones from wastewater samples using rotating disk sorption extraction. After extraction, the concentrated analytes were measured using liquid chromatography coupled with photodiode array detection (HPLC-PDA).

Led by Esther A. Olonimoyo, University of Maryland researchers created a new HPLC-based method for analyzing short-chain fatty acids.
