Direct Elemental Analyses of Ink on Paper by Laser Ablation ICP-MS (PDF)
February 14th 2003The CETAC LSX-500 Laser Ablation System is suitable for trace element microanalysis of virtually any solid sample. Here CETAC Technologies describes the use of the LSX-500 for elemental analysis of inks on paper. For more information, visit the company's website at www.cetac.com.
Unique Atomic Spectroscopy Aims at Answering a Universal Question.pdf
January 1st 2003There is far more matter than antimatter in our universe, but scientists don?t know enough about the properties of antimatter to understand why. By spectroscopically analyzing atoms created when antiprotons collide with helium, physicists at CERN are measuring the properties of antimatter with unprecedented accuracy.
Detection of g-Hydroxybutyrate and g-Butyrolactone by Ion Mobility Spectrometry (PDF)
November 1st 2002The authors discuss g-hydroxybutyrate (GHB), a drug of abuse that is not detected in the drug-detection mode or positive polarity of commercial ion mobility spectrometers, but can be detected by ion mobility spectrometry (IMS) instruments in negative mode.
