Infrared (IR) Spectroscopy

Recent developments in sample inlet systems, improved software, and the advent of special purpose mass spectrometers have improved the utility of MS instruments. here, the authors discuss this new utility.

Here the author compares near-infrared to mid-infrared as analytical tool in process management. he weighs the pros and cons of both spectral regions and suggests general applications for which one or the other is better suited.

IR imaging provides a new tool for disease detection, revealing compositional and structural information in tissue previously not available with contrast staining.

A report published earlier this year (1) discussed a UV–vis-NIR instrument designed for use on NASA Mars rover missions. This article follows up with coverage of the Planetary Fourier Spectrometer on the European Space Agency's Mars Express orbiter mission.

The authors describe their work characterizing archaelogical ceramics by means of Fourier-transform infrared (FT-IR) absorption. Semiquantitative analyses using the technique can identify the main components and trace elements constituting the ceramics. An accurate knowledge of the chemical composition of the samples gives useful information for their classification.

Encoded photometric technology has the ability to address the demands of modern process applications, including those of the PAT initiative.

The authors discuss progress in near-field IR microspectroscopy using a photothermal probe and show how it can be applied to the spectroscopic characterization of real-world samples.

Infrared technology was used as a method for rapid detection of potential Severe Acute Respiratory Syndrome.
