Collection apparatus, measurement system, collection method, and measurement method for particulate material

Abstract

A collection apparatus collects particulate material generated by frictional contact. The collection apparatus includes: a suction duct section that sucks air containing the particulate material; a rectifier section that rectifies a flow of air inside the suction duct section to a laminar flow state; an exhaust section that discharges the air sucked into the suction duct section to outside the suction duct section; and a collection section that collects, within the suction duct section, air flowing inside the suction duct section in the laminar flow state.
