AN AUTOMATED ANALYZING APPARATUS FOR MEASURING WATER QUALITY WITH A CYLINDER-SHAPED SYRINGE UNIT

摘要

The present invention provides an automated analyzing apparatus which comprises: a syringe unit for inhaling or transferring liquid such as sample; reagents and washing solution by moving the piston (12) by a certain distance; a built-in stirring bar (31) located within the syringe barrel (11); a driving unit for rotating the stirring bar (31); a driving means (13) for moving the piston (12) up and down; several connection paths (15a-15f) located in the lower part of the syringe barrel (11) or in the piston (12) where the sample, the reagents, the washing solution, and air can be provided or discharged; 2way on/off valves (16a-16f) connected to each connection path (15a-15f); detecting means (3) positioned in the outer wall of the syringe barrel (11) perpendicular to the piston shaft (14); additional heating and cooling unit (4) for temperature control or sample digestion; control unit (6) for controlling the driving means (13), the detector (2) and valves (16a-16f) described above.
