 Selecting an Excitation Wavelength for Raman Spectroscopy
David Tuschel
We examine the problem of photoluminescence from the material being analyzed and the substrate on which it is supported. We then explain how to select an excitation wavelength that does not generate photoluminescence, reduces the noise level, and yields a Raman spectrum with a superior signal-to-noise ratio.

Replacing Traditional Heavy Metals Testing with Modern Plasma-Based Spectrochemical Techniques
Robert Thomas
The American Chemical Society's (ACS) book on reagents and reference materials, Reagent Chemicals, has become a reference worldwide for the chemicals used in high-purity applications. In the new 11th edition of the book, various updated methods and new procedures have been adopted. Of particular importance are the new plasma-based spectrochemical methodologies for the determination of heavy metals in reagent chemicals.

A Convenient Alternative to MALDI and ESI
Sarah Trimpin, Beixi Wang, Corinne A. Lutomski, Tarick J. El-Baba,
and Bryan M. Harless
As was demonstrated by ESI and MALDI, and, more recently, ambient ionization approaches, successful new ionization methods can have an enormous impact on science. Novel ionization processes, such as inlet and vacuum ionization, are some of the latest of these approaches, and provide excellent alternatives to traditional methods.
