Abstract:

The nature of this collaboration is to build an accurate ion mobility spectrometry IMS instrument with the goal of measuring the reduced mobility K0 of compounds of interest, such as explosives and volatile standards, to an accuracy of or - 0.002 cm2V-1s-1 an order of magnitude higher than the currently accepted level. A database of the K0s of compounds of interest under various temperatures, pressures, drift gas water content levels, and electric fields will be created and referenced by field deployed instruments in order to improve their own accuracy and reduce their false positive alarm rates. This report details the technical and metric data for fiscal years 2013 and 2014.
