Abstract

In an apparatus for fluid analysis, a plurality of reagent-mixture components are each injected by a respective pump through a valve matrix and into a flow-injection unit. The flow-injection unit defines a mixing chamber including a plurality of. As the reagent-mixture components are injected into the mixing chamber, the nubs agitate the fluid flow, thereby dispersing the reagent-mixture components and in turn mixing the components together to create a reagent mixture. The flow rates of the reagent-mixture components are adjusted in order to select the reagent-mixture ratio as the components are combined in the flow-injection unit to thereby create the selected reagent mixture. Upon passage through the flow-injection unit, the reagent-mixture is injected into a sensing unit for analyzing a particle distribution of the mixture.
