ABSTRACT:
For the determination of filterable pollutants in gases there is a filter sc, which is located on a horizontal, compact rotary plate, which is moved over a suction head, whose suction lips interact with corresponding holes or borings in the rotary plate. The suction head is pushed upon from underneath by action of a universal-joint spring bearing against the plane-parallel rotary plate. Preferably, the rotary plate is rotated each time in steps at determined cycle times, specifically according to a program, by a determined number of collection spaces with "phase-shifted" multiple rotations of the plate, until the filter surface is completely used up. Instead of a filter disc, absorber material can also be used for radioactivity monitoring with a forward motion cycle of 1 to 2 days. Three detectors are provided, with the first detector being typically disposed above a first space, the second detector disposed above a space three spaces from the first space, and the third detector disposed above a space eleven spaces from the first space, for example, if the rotary plate is always moved forward by 2 spaces after the accumulation of the specimen in the first space.
