Abstract

The analysis of complex samples without extensive preparation steps (e.g., filtration or centrifugation) is a persistent challenge for applications ranging from forensic identification to high-throughput security screening. Here, a capillary-based microfluidic electrophoresis platform incorporating a hydrodynamic counterflow and capacitively coupled contactless conductivity detection is employed for the detection of inorganic components from propellants, pyrotechnics, and homemade fuel-oxidizer explosives. The bulk counterflow prohibits capillary clogging by particulate or fiber debris, as well as system fouling from fuels, e.g., petroleum jelly or kerosene.
