  • Patent number: 4673295
    Abstract: In a method and an apparatus for performing routine analyses such as polarographic or spectrophotometric analysis on a large set of sample solutions filled into separate sample cups being arranged on or shaped in a sample cup holder (101) along a moving path, wherein the samples are in consecutive cycles sucked out of the sample cup (102) by a suction tube (103) and transferred into a common vessel, wherein the analysis will be performed. The vessel (105) has a lower outlet (107) communicating with an analyzer cell (112) or the ambient space over a channel (116) which is only effective if the sample level in the vessel (105) exceeds a certain threshold level, and an aspirating mouth (108) in the upper part of the vessel (105) communicating over a valve (109) with the ambient space. The suction tube (103) has a fixed end coupled to the inlet (106) of the vessel (105) and a free end can be moved into two different working positions.
