Procedure:
With a spinning disc the test aerosol (Potassium iodide 1.5% in Ethanol) is spread inside the Mars-

to pass the air curtain.
Four Air Samplers each with a filter membrane, catch particles which escape through the air curtain.
With a developing agent (Palladium chloride 0.1%) particles deposited on the filter membrane will
show up as brown spots. The amount of spots is to be counted.
