For the third international Round Robin verification |
|
exercise executed in the fall of 1991 the TNO-Prins |
|
Maurits Laboratory prepared the samples consisting of |
|
rubber, paint and concrete. These materials, which were |
|
selected to represent samples taken during an inspection |
|
at a military facility, were spiked with mustard gas and |
|
related vesicants as well as with decomposition products |
|
of mustard gas. Diesel fuel and an aromatic white spirit |
|
were added as a chemical background. In addition to a |
|
description of the spiked materials, details about the |
|
coding and transportation of the samples are presented. A |
|
number of procedures was developed for the analysis of |
|
the samples. Rubber, which was spiked with mustard gas |
|
and its disulphide, could either be analysed by |
|
extraction with a nonpolar solvent or by |
|
thermodesorption. The latter procedure had advantages for |
|
the analysis by gas chromatography-mass spectrometry (GC- |
|
MS). Paint was spiked with sesquimustard (Q) and |
|
dimustard ether (T). Determination of these compounds was |
|
based on extraction with a nonpolar solvent, followed by |
|
spectrometric analysis (GC-MS, NMR). Concrete was spiked |
|
with two polar decomposition products of mustard gas viz. |
|
thiodiglycol and its sulphone. Extraction with water |
|
followed by analysis with thermospray- liquid |
|
chromatography-mass spectrometry (TSP-LC-MS) turned out |
|
to be the best method for the quantitative determination. |
|
All compounds added were rather stable in the materials. |
|
After a period of 7 weeks they could still be recovered |
|
with reasonable or even good efficiencies. Mustard Gas, |
