Scientists at Oak Ridge National Laboratory have demonstrated that a fast, laser-based mass spectrometry method—LA-ICP-TOF-MS—can accurately detect and identify airborne environmental particles, including toxic metal particles like ruthenium, without the need for complex sample preparation. The work offers a breakthrough in rapid, high-resolution analysis of environmental pollutants.

Quantitative Mass Spectrometry Part III: An Overview of Regression Analysis
March 1st 2008Columnist Ken Busch presents the third of a five-part series on quantitative mass spectrometry. In this installment, he focuses on an overview of regression analysis for calibration lines and curves in mass spectrometry.
Market Profile: Portable Mass Spectrometers
February 1st 2008The concept of portable mass spectrometry has been around for some time, but the realization of such technology has been largely limited until very recently. More than ever before, recent technological advances now make smaller, lighter, and more effective mass spectrometers possible. Such advances will lend themselves to a growing spectrum of applications as well.
Quantitative Mass Spectrometry: Part II
October 1st 2007In this month's installment, columnist Ken Busch continues his discussion of quantitative mass spectrometry with a look at the "cancel out" claim and some of the statistical underpinnings for the proportional comparison of instrument responses for standard knowns and unknowns.
In this article, the role of a triple-quadrupole mass spectrometer in performing in vitro studies of compound metabolic stability and identification of Phase I and II metabolites is demonstrated.
Spectroscopy Demand Expected to Outpace the Industry in 2006
March 1st 2006Realistically, 2005 was a good year for the laboratory analytical and life science instrument industry. Although growth has moderated from that experienced in the 1990s, a general rebound in worldwide industrial demand, and continued spending for life science and strong growth in Asia and North America drove instrument systems and aftermarket sales. Similar to last year, 2006 should be a year of healthy sales growth as global economic conditions support continued market expansion.
