<p>In an extraction unit, a blowing nozzle (3) and a suction channel (7) are embedded in, or integrated into a plate (2) of which the side (2') facing the vessel under investigation, is of planar construction. The plate is heated, at least at the nozzle and/or the suction channel. The suction channel runs against the vessel starting from its entry formation on the plate (2). It includes an angle of 40[deg] seen in normal projection, and is transverse to the vessel (F). Observed in the plane of the flat side of the plate, an angle (beta ) of 30[deg] is included by the channel. Nozzle and/or suction channel diameter is ca. 2 mm. The suction channel opening is placed ca. 10-12 mm behind that of the blowing nozzle, measured along the vessel. A transfer system has an opening edge spaced ca. 6 mm from the plane side of the plate parallel to the nozzle, running continuously past the suction channel.</p> |
