Evaluation studies of a sensing technique for electrostatic charge polarity of pharmaceutical particulates

Electrostatic charge due to inter-particle and particle-to-wall contacts may generate significant hazards during the processing of particulates within the pharmaceutical industry. Although charge behaviour of particulates is erratic and not easy to predict, it would be desirable to characterise the tendency of tribocharging prior to manufacturing. The work reported in this study concentrates on a new and novel technique for the detection of the...
