Developing a Miniaturized Atmospheric Pressure Glow Discharge Source for Atomic Spectroscopy and Desorption Ionization Mass Spectrometry
Ken Marcus and his group at Clemson University have developed a miniaturized liquid sampling atmospheric pressure glow discharge source. Originally designed for atomic spectroscopy, the source actually works for both elemental and organic mass spectrometry. It can operate in various types of solutions, from the acidic to the saline, without ion suppression, and is small and portable.

Vibrational Spectroscopic Imaging: Theory, Application, and Advances
Rohit Bhargava, the winner of the 2012 FACSS/SciX Innovation Award, explains new research into the theory of vibrational spectroscopic imaging that can lead to the development of instruments with new capability for both IR and Raman imaging, for use in various fields, including disease diagnosis.

Nanometer-Scale Studies Using Tip Enhanced Raman Spectroscopy
Volker Deckert, the winner of the 2013 Charles Mann Award, is advancing the use of tip enhanced Raman spectroscopy (TERS) to push the lateral resolution of vibrational spectroscopy well below the Abbe limit, to achieve single-molecule sensitivity. Because the tip can be moved with sub-nanometer precision, structural information with unmatched spatial resolution can be achieved without the need of specific labels.

Screening by LC–MS-MS and Fast Chromatography: An Alternative Approach to Traditional Immunoassays?
Special Issues - May 1, 2013
A new technique was developed based on liquid chromatography coupled with tandem mass spectrometry to analyze drugs that are not part of current immunoassay screening, specifically zolpidem, zopiclone, and zaleplone, or "z-drugs." This method allows for the simultaneous quantification of the z-drugs and all major benzodiazepines in human urine samples.
