Abstract

Abstract : DOI: 10.1002/elps.202000279 The cover picture shows separation and detection of anions from inorganic‐based propellants, pyrotechnics, and explosive samples by gradient elution moving boundary electrophoresis (GEMBE). The GEMBE design includes two reservoirs separated by a microfluidic capillary. Pressure‐driven flow toward the sample reservoir excludes particulates and problematic components, eliminating sample cleanup or filtration. As the pressure is reduced over time, charged analytes electrophoretically enter and migrate through the channel, detected as step changes in conductivity.
