IR Spectral Interpretation
A 12-step program to help you be more successful at interpreting IR spectra
Lasers and Optics Interface
Rapid detection of coal and fly ash is significant for improving the efficiency of thermal power plants and reducing pollution. LIBS has great potential for on-line measurement in these applications.
Spectroscopy Spotlight

Uwe Karst of the University of Münster in Germany discusses his group’s work using ICP-MS for applications such as analyzing magnetic resonance imaging (MRI) contrast agents in river water, speciation analysis in a study of a disease related to renal failure, and examining the distribution of a labeling compound in mouse tumor cells and macrophages.
Peer-Reviewed Article
The performance of a new SERS substrate is tested for trace detection of a pesticide.

Matrix effects in ICP-OES and ICP-MS often cause signal suppression, but can lead to signal enhancement as well. Guillermo Grindlay of the University of Alicante, in Spain, discusses his work to better understand under what conditions these matrix effects occur and what mechanisms are involved.

Annemie Bogaerts and Maryam Aghaei of the University of Antwerp, Belgium, are carrying out computational modeling to examine how various properties of the ICP, such as gas flow path lines and ionization effects, are affected by various factors—such as gas flow rates, applied power, and even the very presence of a mass spectrometry sampler. Using their developed model, one can predict optimum conditions for specific analyses.
