A microstructured capillary electrophoresis method for nitrocellulose detection in dynamite

In this article we present a microstructured-capillary electrophoresis method for the determination of minimal amounts of nitrocellulose in dynamite samples. A 6-hole microstructured capillary (MSC) was selected for the method development. First, the hydrodynamic behaviour of the MSC was studied at...

description In this article we present a microstructured-capillary electrophoresis method for the determination of minimal amounts of nitrocellulose in dynamite samples. A 6-hole microstructured capillary (MSC) was selected for the method development. First, the hydrodynamic behaviour of the MSC was studied at varying lengths (31, 41 and 51 cm), which had never been studied before. Next, one of the MSC segments (31 cm) was employed to develop a microstructured-capillary electrophoresis method to determine nitrocellulose in dynamite. In a first evaluation, the dynamite derivatization process was investigated to obtain an efficient derivatization yield.
