In addition to expressing his longing for a Star Trek "tricoder," columnist Ken Busch shows that the core processes of ionization, ion dissociation, and mass determination in mass spectrometry are all completed in very short times compared to the overall length of the analysis.

This month's "Focus on Quality" presents a critique of the GAMP Good Practice Guide. And while columnist Bob McDowall finds much to recommend in the guide, he finds much more cause for concern.

Surface-enhanced Raman spectroscopy (SERS) is a widely studied technique capable of adding single-molecule detection capability to the rich information provided by Raman spectroscopy. in this aricle, the authors show an additional system gain of more than two orders of magnitude to SERS by using a dielectric microsphere resonator to capture and excite the target system.

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.

The worldwide market for aftermarket products and service for laboratory molecular spectroscopy was worth more than three-quarters of a billion dollars in 2005, representing quite a significant market in its own right. The aftermarket, which accounts for the majority of this market, consists largely of similar products across the varying molecular spectroscopy techniques. Demand for service is for the most part dependent upon the complexity and cost of the initial systems.
