Guest author Art Springsteen discusses standards for reflection measurements and the issues surrounding this topic.

Lifetime fluorescence is a significant niche market within the larger category of fluorescence spectroscopy. Although the current scope of application is fairly limited, the potential is quite significant. The range of competition in this area is fairly small, but is expanding.

November 2006. The authors demonstrate the use of NIR-CI for simultaneous measurement of content uniformity for multiple tablets and discuss some advantages of this approach.

The European Space Agency brings infrared spectrometry to new heights.

Columnist Bob McDowall proposes an integrated approach to the combined issue of equipment qualification and computerized system validation for spectrometers that combines the qualification, day-to-day calibration, and maintenance of the instrument with the validation of the software for a system?s intended purpose.

November 2006. Raman spectroscopy is a promising new tool for noninvasive, real-time diagnosis of tissue abnormalities. Here, we show evidence of its application for cancer diagnosis in four distinct tissue types: skin, breast, gastrointestinal tract, and cervix. Multivariate statistical analysis and discrimination algorithms allow for automated classification of the spectra into clinically relevant pathological categories using histology as a gold standard. Although limitations exist, the technique shows every indication of being an exciting prospect in the management of cancer in a clinical setting.
