Use of Raman Spectroscopy and 2D-COS for the Detection and Characterization of Chemical Interactions
Fran Adar
Two-dimensional correlation spectroscopy (2D-COS) can reveal subtle chemical interactions that are difficult to discern when analyzing individual spectra. A demonstration of the subtleties of this technique can be seen in the analysis of ethanol–water and ethanol–methanol mixtures.

The Impact of Illegal Artisanal Gold Mining on the Peruvian Amazon: Benefits of Taking a Direct Mercury Analyzer into the Rain Forest to Monitor Mercury Contamination
Robert Thomas
Illegal artisanal gold mining using mercury amalgamation is poisoning people and the ecosystem in the Amazon rain forest. By taking the technique of direct mercury analysis to a remote, field-based laboratory, the team of Professor Luis Fernandez is measuring the extent of the contamination in a wide variety of samples, including soil, fish, air and human hair.

Using Reference Materials, Part I: Standards for Aligning the X-Axis
Jerome Workman, Jr. and Howard Mark
The use of reference materials to align or test the wavelength–wavenumber axis for optical spectroscopy is essential for quantitative and qualitative methods. This article provides details for using reference materials with ultraviolet, visible, near-infrared, infrared, and Raman spectroscopy methods.
