How to select the optimum atomic spectroscopic technique for orally delivered drugs, based on the J-values described in the validation protocols outlined in USP Chapter

Duncan C. Krause, of the Department of Microbiology at the University of Georgia, discusses his group’s work to establish a SERS method with silver nanorod-array substrates for detecting the pathenogenic mycoplasma that causes bronchitis and pneumonia.

Igor K. Lednev, of the Department of Chemistry at the University at Albany, the StateUniversity of New York, has been developing the use of Raman spectroscopy for a varietyof forensic applications, including determining the age of blood stains and linking gunshot residues to specific ammunition–firearm combinations.

Acid anhydrides are unique in that they have two carbonyl groups in them. The intensity and position of their IR peaks can be used to determine which of the four types of anhydride exist in a sample.

This article discusses advances in techniques and modifications to technologies that are improving measurements and enabling well-established techniques to break into new and exciting fields of research.We survey developments in infrared spectroscopy, Raman spectroscopy, X-ray fluorescence spectroscopy, inductively coupled plasma–optical emission spectroscopy, and laser-induced breakdown spectroscopy

Our annual spectroscopy salary and employment survey shows encouraging increases, but in many areas, spectroscopists have simply gained back ground that had been lost in recent years.
