Rapid Classification of Beef Aroma Quality Using SIFT-MSApplication of multivariate statistical analysis to a combined data set demonstrated that SIFT-MS discriminates premium quality beef from eight sensory defects, and, therefore, could be applied as an instrumental grading tool, obviating sensory panel grading.

High-Throughput Analysis of Volatile Compounds in Air, Water, and Soil Using SIFT-MSFor the BTEX compounds, detection limits in the single-digit parts-per-billion concentration range (by volume) are readily achievable within seconds using selected ion flow tube mass spectrometry (SIFT-MS), because sample analysis is achieved without chromatography, preconcentration, or drying.

Standoff, Wide-Area Explosive and Narcotic Detection Using Shortwave Infared Hyperspectral ImagingShortwave infrared hyperspectral imaging (SWIR HSI) shows great potential in the targeting and identification of explosive and narcotic materials in complex scenes where the target concentration is low. Tunable filter–based SWIR HSI sensors can be configured to use either single-bandpass or multiple-bandpass wavelength tuning to enable hazardous material detection in stationary, moving sensor, or moving target scenarios.

External Reflection Analysis of Surface CoatingsExternal reflection using IR spectroscopy is effective for examining paintings, polymer-coated metals like soda can coatings, and even bulk polymers. Shiny, metallic surfaces provide a strong specular reflection spectrum that matches standard absorbance spectra very well. Less-reflective surfaces, like dark plastics, may require additional software processing.

FT-IR Spectroscopy for Identification of Biological Stains for Forensic PurposesFor analyzing unknown biological stains in a forensic setting, Fourier transform infrared spectroscopy has many advantages. It can provide confirmatory identification of the fluid type, can estimate the stain’s age, discriminate species, and can be used on samples found on various substrates and exposed to various environmental conditions.

Advancing Forensic Analyses with Raman SpectroscopyIn recent years, there have been significant advances in the application of vibrational spectroscopy to the analysis of forensic samples. Igor K. Lednev, a professor in the Department of Chemistry at the University at Albany, the State University of New York, has been developing the use of Raman spectroscopy for a variety of forensic applications, including the determining the age of blood stains and linking gunshot residues to specific ammunition–firearm combinations. He recently spoke to Spectroscopy about his work.

Identification of Graphite Mechanical Behavior and Dislocations by Micro-Raman MicroscopyIn this study, micro-Raman microscopy was used to examine graphite mechanical behavior through the evolution of dislocation defect density and the resultant deformation (strain) in graphite components. The increasing strength of the Raman optical phonon modes linked with a generous number of dislocations indicates the potential capability of Raman spectroscopy to help develop a mechanistic understanding of the complex mechanical behavior of graphite for use in many industries and applications.
