Determination of Nitrate Carry-Over on Bytac(registered) Strips Via Capillary Electrophoresis
Abstract
Inorganic explosives including ammonium nitrate, urea nitrate, and ANFO are among the most common energetic materials used in home-made devices. The ability to detect these materials sensitively with low occurrences of false negatives and positives is of paramount importance. As new detection technologies are developed, the need to standardize procedures to evaluate these technologies is equally important. Most technologies include a sampling step; typically a substrate used to swipe a suspect surface. A key performance metric is the transfer efficiency of this sampling step. Capillary electrophoresis was used to quantify the nitrate ion on cardboard-back Teflon strip (Bytac(registered trademark) to establish the transfer efficiency for three inorganic explosives. These results indicate that transfer efficiency is analyte specific, dependent upon the amount of analyte present, and the mechanism of transfer.
