    摘要： An automatic chemistry analyzer includes a flow cell mounted so that flow through the cell and tubing connected to the cell is visible from the front of the housing. The electrolytes to the cell are removably plugged into the cell from their rear. The probe aspirating sample fluid into an injection cell is simultaneously washed by diluent and the diluent mixes with the fluid sample. Waste fluid from the flow cell is fed to a basin which then feeds under gravity to a waste drain. A ratio pump is formed by selected syringes which are band driven to deliver accurately prerequisite volumes of reagents to the flow cell. The solution ground to the system is on the inlet line for sample adjacent the entrance to the flow cell of fluid thereby minimizing electronic noise. Only two motive means are necessary, one to effect horizontal and rotational movement of the sample tray, and a second to effect vertical motion of a crane mounted probe operative between sample cups and an injection cell.

    摘要： An automatic chemistry analyzer comprises discrete sample cups about the circumference of a carousel. A motor selectively moves the sample cups towards and away from a target location where a probe is located for reciprocal vertical motion. The motion is timed for reaction with a sample cup so that when the sample cup is in position at the target location, the probe removes fluid from the sample cup. When the sample cup is moved from position, the probe aspirates fluid into an injection cell below the sample cup. A vertical motion only is imparted to the probe, while the sample cups move under the action of a single motor horizontally and laterally to define a rotational movement.
