Here, a method to characterize edible oils and edible oil mixtures through fingerprinting and the isolation of individual analyte differences is reported. Aroma and flavor analytes in extra virgin olive, olive, peanut, grapeseed, and vegetable oils were sampled with headspace solid-phase microextraction (HS-SPME).

Guido F. Verbeck, an associate professor in the Department of Chemistry at the University of North Texas (Denton, Texas), has been developing a technique called direct analyte-probed nanoextraction (DAPNe). Verbeck is using DAPNe, coupled to nanospray ionization mass spectrometry (MS), in a variety of applications, including forensic analyses. Spectroscopy asked Verbeck about his work with this method and how it is used.

Spectroscopy recently spoke with Dr. Dominic Hare, a senior research officer at the Florey Institute of Neuroscience and Mental Health in Australia, about his work using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) to study metals in the brain. His research highlights the role that iron plays in Parkinson's disease in the hopes to better understand the causes of the disease and eventually find an appropriate treatment.
