An automated analysis method for an impactor used as a measuring transducer for the selective determination of oil mist or aerosols. A discharge flow restrictor 15 is provided in a discharge passage 12 through which a working fluid from the fluid-pressure pump 2 is supplied to fluid-pressure cylinder 3. The pressure sensitive adhesive layer can be a permanently grown pressure sensitive adhesive that has an adhesion force to the breast forms that is greater than a cohesion force to the user’s breasts. A bead 40 seals the reinforcing strip 30 from the environment. Reactants flowing through the gap to the catalyst pad participate in nanotube growth. The applicator is used in the manner of a writing instrument to remove nail polish.
