Abstract
A system includes a reagent selector valve controllable to select a reagent flow path from a plurality of reagent flow paths, and a pump coupled to the reagent flow path to draw a liquid through the reagent flow path in accordance with a prescribed test protocol. The system includes a discharge flow path to expel the drawn liquid, and a flow meter to measure liquid displaced by the pump and that outputs data representative of the measured flow. The system also includes a processor to access the data and to determine a volume of the liquid displaced by the pump.
Claims20
A method comprising:
- implementing a stored test protocol for performing one or more reagent displacement tests, wherein each reagent displacement test includes:
- a) selecting a reagent flow path from a plurality of reagent flow paths;
- b) actuating a pump to draw a predetermined amount of fluid through the selected reagent flow path in accordance with the stored test protocol;
- c) discharging the drawn fluid from the pump and through a discharge flow path;
- d) measuring flow rates of any liquid discharged through the discharge flow path during (c) and generating data representative of the flow rates;
- and
- e) processing the data to determine a quality of the selected reagent flow path.
