Top 16 Articles from 2016
With the arrival of the new year, the editorial team at Spectroscopy presents its annual compilation of the most popular articles of 2016. Included in this list is timely advice from experts on key topics such as IR interpretation, Raman spectroscopy, LIBS, ED-XRF, data integrity, and more.
A 12-step program to help you be more successful at interpreting IR spectra. read more
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. read more

Vassilia Zorba of Lawrence Berkeley National Laboratory discusses what her studies have revealed about the mechanisms of plasma emission at small scales and what she has found when applying femtosecond LIBS to the study of advanced battery materials. read more
Recent advances in instrumentation have enabled new forms of vibrational chemical imaging, including discrete-frequency infrared (DFIR) microscopy and stimulated Raman scattering (SRS) microscopy. These technologies may represent a fundamental shift in how we approach spectroscopic imaging. read more
As analysts prepare to meet the requirements of the new United States Pharmacopeia and International Conference on Harmonization standards on elemental impurities, they need to understand how to choose the most suitable sample preparation approach. read more
Low-frequency Raman spectroscopy offers advantages over XRD or DSC for crystallinity studies. read more
Parameter optimization is illustrated through the determination of titanium in a polymer and the multielement analysis of high-purity graphite using the ashing sample preparation method. read more
Raman spectroscopy has the potential to accurately and nondestructively determine the age of a bloodstain for use in criminal investigations. read more
Data integrity is the currently hottest topic in regulated good practice (GxP) laboratories. Here's what you need to know about the latest guidelines, issued by the FDA in April 2016. read more

The value of combining ATR and transmission spectra for the analysis of polymer laminates is illustrated here through the analysis of a multilayer polymer laminate from a food packaging sample. read more
If you are not trained in Raman spectroscopy, how should you approach interpreting Raman spectra? This article explains what to do, along with some underlying fundamentals to orient you. read more
A detailed explanation of the principle of analysis of variance. read more
A demonstration of the ability for portable Raman spectroscopy, coupled with univariate and multivariate analysis tools in the process development stage, to gain insight and process understanding of chemical reactions. read more
The accurate determination of protein concentration in a drug formulation is a challenge when no reference standard is available. This isotope dilution ICP-MS/MS method based on sulfur determination is fast and allows for very accurate determination of a single protein in solution after microwave digestion. The method is widely applicable. read more
