IDENTIFICATION AND DETERMINATION OF CHEMICAL WARFARE COMPONENTS AND THEIR DECOMPOSITION PRODUCTS USING MASS CHROMATOGRAMS IN CHARACTERISTICIONS AND IN ION MASS-DIFFERENCES

The principal pathways of electron-impact fragmentation were character ized for a number of derivatives of phosphoric and methylphosphonic ac ids under a set of specific ions that permits these compounds to be de tected in complex matrices as found out for each of these groups. It w as proposed to use specific differences between ion masses in mass spe ctra of phosphorus-containing compounds as representative and selectiv e group indicators together with the characteristic ions of these subs tances.
