Author(s)
Jennifer R. Verkouteren, John G. Gillen, R M. Verkouteren, Robert A. Fletcher, E S. Etz, George A. Klouda, Alim A. Fatah, Philip J. Mattson
The purpose of this document is to establish minimum performance requirements and an associated test method for Ion Mobility Spectrometry (IMS) based trace explosives detectors for use by the first responder community. Information concerning the theory and

Standardization of Isotope Ratio Measurements for Doping Control

December 1, 2004
Author(s)
R M. Verkouteren
Pharmaceutical steroids are known to differ in isotopic composition from those produced naturally in the body. By measuring the 13 C/ 12C ratio of specific steroids deteched in urine, the technique of Gas Chromatography-Combustion-Isotope Ratio Mass

Isotopic Metrology of Carbon Dioxide. I. Interlaboratory Comparison and Empirical Modeling of Inlet Equilibration Time, Inlet Pressure, and Ion Source Conductance

June 1, 2003
Author(s)
R M. Verkouteren, C E. Allison, S A. Studley, K J. Leckrone
We report a pilot study of high-precision differential isotopic ratio measurements made on replicate samples of pure carbon dioxide using three instruments of identical manufacture. Measurement protocols were designed to explore the effects of sample size
