Abstract

PURPOSE:To decrease the liquid that sticks in nozzles and dispense a small amount of sample liquid with good accuracy by providing a control unit which changes the running speed of a nozzle moving motor of the time of pulling up the nozzles by the kinds of the sample liquid. CONSTITUTION:A nozzle moving motor 15 is operated to insert a nozzle 7 into sample liquid 10. A syringe 4 for sampling is lowered for a constant stroke by a sampling syringe cam 13 so that the sample liquid is sucked at a fixed amount by the nozzle 7. After this, the nozzle 7 is inserted into the hole of a carbon tube cell 11 by the nozzle moving motor and the sampling syringe operates to discharge the sample liquid. A control unit 20 consists of an input part 17 and a control circuit 16, and depending upon whether the sample liquid is an aqueous soln. or a blood serum, or org. solvent sample liquid, the unit changes over the change-over terminal parts of the input part and operates a control circuit 16, which in turn changes the speed at which th nozzle moving motor 15 is pulled up from the sample liquid.
