Focus on Quality
Thinking about data integrity in four layers makes it easier to fully understand the overall scope and complexity of this topic. It also facilitates proper implementation of data integrity programs to ensure effective regulatory compliance.
Lasers & Optics Interface
Vincent Motto-Ros of Lyon 1 University in France is combining the ability of atomic spectroscopy techniques to detect and quantify metals with the mapping approaches most often used with molecular techniques. Here, he discusses his work applying LIBS to biological analysis, including the methods, advantages, and future directions.
Spectroscopy Spotlight Interviews
By Spectroscopy Editors
Benoît Igne, a principal scientist at GlaxoSmithKline, discusses his work using NIR and areas where he thinks the technique has growth potential, specifically process analytical technology and agriculture.
By Spectroscopy Editors
Ralf Ostendorf of the Fraunhofer Institute for Applied Solid State Physics in Freiburg, Germany, discusses his work using a miniaturized QCL, which when used as a light source, enables mid-IR scanning speeds much faster than those of conventional FT-IR.
Peer-Reviewed Article
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.
Application Notes (Advertising Content)
The characterization of the active pharmaceutical ingredient (API) and its distribution and physical properties in commercial medicine is necessary in drug research and development process in the pharmaceutical industry. Among various analytical techniques employed for this purpose, Raman spectroscopy is gaining more popularity due to its advantages as non-destructive, non-invasive, fast spectrum acquisition in seconds, high reproducibility, and so on.
Miniature X-ray sources reached the development level that is appropriate for their use in the hand held and portable X-Ray diffraction (XRD) instruments. This note describes the application of X-ray sources for the residual stress measurements using XRD.
Protein secondary structure during thermal unfolding and aggregation is readily acquired using IR spectroscopy and a temperature-controlled mid-IR transmission accessory. Myoglobin was used as a model system to illustrate the method.
