COLUMNS
Mass Spectrometry Forum: Underwater Mass Spectrometry
Kenneth L. Busch
In this column, we first describe the use of mass spectrometers in submarines, and their more recent use for direct sampling of compounds dissolved in water at ever-increasing depths.

The Baseline: Little Points of Light
David W. Ball
Virtually everything we know about stars is based on spectroscopy. Here, David Ball explores what spectroscopy tells us about magnitude, red shift, and why the night sky is dark.

Laser and Optics Interface: Multi-Photon Laser Techniques for Medical Imaging and Diagnostics
Youngjae Kim, PhD, Alain Villeneuve, PhD, Joseph Salhany, PEng, Genia Photonics Inc.
This month’s column describes various multi-photon techniques and applications, including a discussion of the technologies typically used and what the newest lasers offer.

ARTICLES
ICP-MS A Preliminary Investigation of Toxic Trace Metals in Pet Foods Using Cryogenic Grinding and Quantitation by ICP-MS — Part I
P. Atkins, L. Ernyei, W. Driscoll, R. Obenauf, R. Thomas
This study examined pet foods from a variety of sources to determine if there were potentially toxic elements present in the foods and also whether more expensive foods with higher quality ingredients equated to lower levels of toxic elements. Part I focuses on the raw materials used in the pet food manufacturing processes and all the potential sources of contamination, and discusses the analytical methodology used to determine the trace element content of the pet food samples, including the sample preparation steps and the optimum ICP-MS instrumental conditions for the analysis.

FTIR / LASERS & OPTICS An Optical Nose Approach to Explosive Detection: One Strategy for Optically Based Sensing
Tabetha Osborn, William A. Burns, Joshua Green and Scott W Reeve, Department of Chemistry and Physics and the Arkansas Center for Laser Applications and Science (ArCLAS), Arkansas State University
Adopting the explosive bouquet concept from the canine research field, we have begun to systematically examine, at high spectral resolution, the vapor from volatile impurities commonly found in explosives. While the high resolution spectra for many of these compounds is quite complex, through careful scrutiny and evaluation of individual vibrational bands, spectral regions with potential for sensing and/or detection applications have been identified. Here, we discuss one such example with potential applications to the military grade explosive known as composition C4.
