Abstract
An apparatus and method are provided for the precisely controlled and coordinated, concomitant supply at optimal flow rates, by differential pumping, of selected sample and sheath liquids from respective pluralities of different sources thereof, to the same sheath stream flow cell for successive different types of sample analyses, thereby maximizing sample analysis accuracy and reproducibility, and reducing apparatus complexity and costs. The apparatus and method are particularly useful in high-speed automated biomedical analytical systems.
