Abstract
Method for analysing a device for spraying a pharmaceutical fluid, including the steps of providing a spray head having a spray opening; providing a receiving surface having a perforated plate having a plurality of holes, each hole being associated with a ball that is guided through a guide channel until reaching a transparent pane behind which a camera is arranged; charging the perforated plate with an electrostatic charge to attract the balls to the holes; passing a gas stream through the spray head and sending it onto the receiving surface, the balls that are hit by the gas stream being moved to the pane; visualising the impact zone for the compressed gas stream on the receiving surface that is formed by the balls that have been moved to the pane; and analysing the visualisation of the impact zone to determine whether or not the impact zone complies with predetermined specifications.
