Triboelectrification of pharmaceutical powders with stainless steel and polymer contact surfaces was investigated. alpha-Lactose monohydrate, from 90 to 125 up to 355-500 microm, was used to quantify electrostatic interactions with negligible powder adhesion to the contact surface. Size fractions down to 53-75 microm alone and in binary mixtures with <10 microm lactose or micronized salbutamol were used to investigate triboelectrification with powder adhered to the contact surface… CONTINUE READING
