National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

FT-IR Analysis of Chemical Warfare Agents.

ADA208192

Publication Date	1988
Personal Author	Braue, E. H.; Pannella, M. G.
Page Count	7
Abstract	The qualitative and quantitative FT-IR analyses of dilute aqueous solutions of GA (tabun), GB (sarin), GD (soman), and VX were evaluated using the CIRCLE CELL. Infrared spectra were recorded using a Nicloet 60SX FT-IR spectrometer fitted with a liquid nitrogen-cooled MCTA detector. The CIRCLE CELL used a high pressure reflection element. Peak heights were evaluated with the Nicloet SUPER QUANT program after spectral subtraction of the solvent. The P=O stretching absorption band, centered around 1240 cm-1 for the G-type agents and 1180 cm-1 for VX, produced good quantification. At a concentration of 2.0 mg/ml for the G-type agents and 1.0 mg/ml for VX, quantitative analysis produced coefficients of variation of 3% or less. The detection limit was observed to be around 0.1 mg/ml. Reprints. (aw)
