Claims9
A method of assaying an analyte presence in a liquid sample, the method comprising:
- directing a liquid sample into a plurality of capillary spurs in fluid flow communication with a single main flow channel, each capillary spur including a titration cell from a plurality of titration cells, each titration cell from the plurality of titration cells containing a sensor, each titration cell being a flow-through titration cell;
- titrating a first quantity of a reagent into a first titration cell from the plurality of titration cells;
- titrating a second quantity of the reagent into a second titration cell from the plurality of titration cells;
- and
- calculating an amount of an analyte in the liquid sample based, at least in part, on the first quantity of the reagent and the second quantity of the reagent.
