Abstract

The distributor comprises a slide valve having a moving part (12) and a fixed part (13) fitted with orifices or holes (16, 17, 18 and 19, 20, 21) each connected to the sampling tube (1), to one or more analysis tubes (3), to a pneumatic source and to a liquid pump (22). The moving part (12) of the valve has a channel of known volume (14) and pref. one or more supplementary channels (15). Liquid is introduced to fill the channel of known volume (14) and the moving part (13) is displaced in a forward and return motion w.r.t. the orifices so as to transfer successively the quantity defined by the channel (14). The various pipes involved are washed and dried utilising the pneumatic source and the liquid pump.
