Stress, Strain, and Raman Spectroscopy
David Tuschel
When stress is applied to an object, it can produce strain. Strain can be detected through changes in peak position and bandwidth in Raman spectra. Here, we show examples of how strain in technologically important materials appears in the Raman spectra.

Applications of ICP & ICP-MS Techniques for Today's Spectroscopist
Arsenic Speciation in Krill and Other Marine Oils by Liquid
Chromatography–Inductively Coupled Plasma-Mass Spectrometry
Katarzyna Banaszewski, Anna Plocicka-Okladlo, and Aaron Secrist
An arsenic speciation method using LA–ICP-MS was developed to provide a more accurate procedure for the determination of arsenic species in marine oils. It was validated for the analysis of five arsenic species in krill oil, and should also prove useful when quantitating inorganic arsenic species in other marine oils.

Method Development with ICP-MS/MS: Tools andTechniques to Ensure Accurate Results in Reaction Mode
Ed McCurdy, Glenn Woods, and Naoki Sugiyama
Method setup and optimization steps are explored to illustrate how an ICP-MS/MS method can be defined and tested to ensure consistent performance. Users can benefit from improved interference removal performance without the complex method development inherent in the use of ion-molecule reaction chemistry.

Development of an Analytical Method to Determine Chromium, Iron, Nickel, and Zinc in Mouthwash by ICP-OES and Assessment of Possible Metal Migration from Stainless Steel
P.M.F. Camargo Filho, J.F.S. Joca, and I. Gaubeur
A simple analytical method, requiring no sample pretreatment, was developed
for determination of chromium, iron, nickel, and zinc in mouthwash by inductively
coupled plasma‒optical emission spectrometry (ICP-OES). This method allowed
the study of potential migration by iron, chromium, and nickel from stainless steel
containers.
