The samples measured by static image analysis typically rest on a slide that is moved by an automated stage. With the PSA 300 static image analysis system a microscope and digital camera collect images of the particles as the slide is scanned. Samples prepared on slides can include powders, suspensions, or scanned. Aerosol delivery forms such as metered dose inhalers or dry powder inhalers can be inspected using static image analysis by actuating the device onto a slide for measurement. In addition, particles in suspension (such as parenterals) can be collected on a filter for characterization.
