Seeing Things That Have Never Been Observed Before: Pushing the Limits of Mass Spectrometry
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. Spectroscopy recently spoke with Clemmer about this work.

Surface-Enhanced Raman Spectroscopy: Fundamental Research and Practical Applications
Surface-enhanced Raman spectroscopy (SERS) enhances the Raman signal using molecules adsorbed on rough metal surfaces. This interview with 2014 Charles Mann Award winner Richard P. Van Duyne of Northwestern University discusses his group's work with tip-enhanced Raman spectroscopy, single-molecule SERS, a SERS system for glucose analysis, and SERS as a method for analyzing colorants in artworks.

Understanding Biological Systems at the Quantum Level Using 2D Electronic Spectroscopy
Spectroscopy recently spoke to Greg S. Engel, who is an Associate Professor in the Department of Chemistry at the University of Chicago in Chicago, Illinois, and one of the winners of the 2013 FACSS Innovation Awards. Here, Engel discusses his research examining quantum dynamics in biology, chirality in dynamics, and the use of two-dimensional electronic spectroscopy.

Putting a Spectrometer on a Cell Phone
Will your next cell phone include a spectrometer? In this interview, Alexander Scheeline talks about what is involved in creating such a device, and his work toward that end. This interview is part of Spectroscopy's 2014 interview series with the winners of awards that are presented at the SciX conference.

Laser-Induced Breakdown Spectroscopy: A Closer Look at the Capabilities of LIBS
Spectroscopy - July 1, 2014
Dr. Richard R. Hark, a professor in the Department of Chemistry at Juniata College in Huntingdon, Pennsylvania, discusses his work with LIBS in applications such as forensic science, conflict minerals, and geochemical fingerprinting.
Rapid Determination of Trace Metals in Oil Using Handheld X-Ray Fluorescence Spectroscopy
Spectroscopy - July 1, 2014
Determination of trace metals in oil and petroleum typically is based on ICP-OES methods, requiring signficant sample preparation and expensive instrumentation. This article presents an alternative method, based on the use of a handheld energy-dispersive X-ray fluorescence analyzer, that involves minimal sample preparation, uses authentic standards for calibration, gives low parts-per-million detection limits, and provides significant time and cost savings.
Determination of 2-Hydroxy-4-(methylthio)butanoic Acid in Bovine Serum and Sea Water
Special Issues - July 1, 2014
Simple, sensitive, rapid, selective, and precise reversed-phase liquid chromatography (LC), electrospray ionization mass spectrometry (ESI-MS), and tandem MS (ESI-MS-MS) methods were developed and validated for the determination of 2-hydroxy-4-(methylthio)-butanoic acid (HMTBA) in bovine serum and sea water matrix. HMTBA is the ?-hydroxy analog of the sulfur-containing amino acid methionine and is extensively used as a methionine supplement in poultry and bovine feed.
LC–MS Identification of Wax Esters in Cloudy Canola Oil
Special Issues - July 1, 2014
Canola largely contains unsaturated fatty acids, thus rendering it clear in most cases after extraction and refining.
