Mass spectrometry is a powerful analytical tool. Yet researchers and instrument makers continue to push the limits of its resolving power. One such researcher is David E. Clemmer, the Robert & Marjorie Mann Chair and Distinguished Professor of Chemistry at Indiana University in Bloomington, Indiana and the 2014 Anachem Award winner. Clemmer's group has done extensive research to develop and improve ion trapping techniques and ion mobility spectrometry-mass spectrometry (IMS-MS) instruments to analyze biomolecular mixtures and structures.

Translational proteomics has not been as successful as originally anticipated. Because mass spectrometry (MS) can separate proteins at the sequence level, it provides the selectivity needed for this application; however, traditional challenges still exist, including time-to-result, throughput, and sample-size requirements.

Despite the advantages of soft ionization ion-source technologies for improving confidence in the identification of a range of challenging analytes, soft ionization remains a niche technique for gas chromatography–mass spectrometry (GC–MS).

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).

The production and sale of counterfeit drugs has risen sharply in recent years. The World Health Organization (WHO) estimates that counterfeit medicines account for approximately 1% of sales in developed countries and well over 10% in developing countries.

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.
