Abstract
In conventional devices for feeding an analysing apparatus with different media, comprising a feeder unit with fittings for the media to be introduced, the individual media travel different paths between the inlet opening and the measuring chambers, which will result in different conditions of measurement for calibrating media and sample media. The invention eliminates this drawback by providing the feeder unit (1) with feed elements (4, 4') connected with the fittings (5), and by enabling each feed element (4, 4') to be positioned above the sample inlet opening (10) by means of a control unit (8) effecting a translational or rotatory motion of the feeder unit (1), subsequent to which the feed element (4, 4') can be inserted into the sample inlet opening (10) by means of a lifting device acting parallel to the center axis (11) of the sample inlet opening (10).
