Spectroscopy Spotlight
In biology, the study of intracellular structures is important and requires analytical techniques with submicrometer resolution. Atomic force microscopy-infrared (AFM-IR) spectroscopy is one technique that has the required lateral spatial resolution to observe such structures. David Perez-Guaita, PhD, at the Centre for Biospectroscopy at Monash University in Australia, is pioneering work applying AFM-IR to the study of red blood cells infected with the malaria parasite. read more

FRONT & CENTER - Physical Property Testing: Getting the Right Answer with History and Hundreds of Million Dollars at Stake
Many analytical tools can be used to determine the physical properties of materials such as gas and liquid chromatography, and atomic absorption spectroscopy. However, molecular spectroscopy, both infrared (IR) and Raman, are among the most powerful tools available to the analytical scientist.

Raman spectroscopy is a convenient method for probing the chemical bonding and solid state structure of crystals, and it is sensitive to the presence of dopants, impurities, and crystal defects in the host-crystal lattice. Here is what you need to know about how a host-crystal Raman spectrum is affected by dopants and impurities.

Microplastic characterization by Raman imaging spectroscopy
This white paper discusses an improved method for identifying and quantifying microplastics in the environment, a growing health risk to wildlife and humans. Problems occur when microparticles below 20 microns cannot be accurately characterized using conventional methods. Review data showing how these problems are overcome by using Raman imaging spectroscopy.
