ABSTRACT:
A sample liquid is sucked into a nozzle which is mounted at a front end of an arm. Then the arm is moved down to a position where the sample liquid is discharged from the nozzle so as to form a drop on the lower end of the nozzle. Thereafter the arm is further moved down at a speed not higher than 40 mm/sec to a position where the drop comes into contact with a chemical analysis element.
