✦ Synopsis

A method for the rapid quantitative determination of 2,4,6-trinitrotoluene (TNT) is described. This method uses a Barringer Ionscan, an instrument based on ion mobility spectrometry (IMS) technology, as a detector. IMS is usually employed to provide semiquantitative results in a very short analysis time. An extensive statistical analysis of quantitative results has been carried out for this study, and a linear response between 300 pg and SO00 pg TNT has been characterized. Detection of TNT within 0.2-1.0% of the true value was obtained with this method.
