Methods of detecting and identifying munitions compounds |
摘要 |
HPLC methods for detecting, identifying and quantifying munitions compounds or munitions materials are disclosed. Insensitive munitions explosives (IMX) can be detected along with conventional munitions compounds such as 2,4,6-trinitrotolene (TNT) in a single column analysis. The methods are also useful to provide analytical evaluation of soil samples, aqueous samples such as ground water samples and tissue samples containing insensitive munitions explosives (IMX). |

1. A liquid chromatographic method for separation of mixtures comprising at least a first explosive compound and a second explosive compound, said method comprising the steps of:
(a) providing a sample comprising at least said first and second explosive compounds, wherein said first explosive compound is a nitroaromatic and said second explosive compound is selected from the group consisting of nitroguanidine (NQ) and nitrotriazalone (NTO), (b) combining said sample with an initial acidic carrier solvent to form a sample solution, said initial acidic carrier solvent comprising less than about 99 % by volume water and alcohol, acetonitrile in an amount ranging from about 0% to about 5% by volume, and 1% or less by volume of an acidic component, said initial acidic carrier solvent having an initial volume % water and a corresponding initial volume % alcohol, based upon the composition of the initial acidic carrier solvent, (c) passing said sample solution through a liquid chromatography column, (d) continuously lowering said initial volume % water to a final volume % water and a corresponding final volume % alcohol, while continuing to pass acidic carrier solvent through said liquid chromatography column, such that a solvent gradient is established during said method, and (e) separating said at least two explosive compounds in said column. |
