1. An apparatus for at least one of particle and chemical analysis of reagent mixtures having a plurality of reagent-mixture components, comprising:

  • means for pumping each of a plurality of reagent-mixture components in a respective stream at a respective flow rate;

    means for introducing at least one reagent-mixture component into a stream of at least one other reagent-mixture component to mix the plurality of reagent-mixture components into a combined reagent-mixture stream, said means including an elongated mixing chamber defining an upstream end and a downstream end, at least one inlet port located at the upstream end of the mixing chamber and coupled in fluid communication with the pumping means for introducing a plurality of reagent-mixture component streams into the mixing chamber, an outlet port located downstream of the at least one inlet port for receiving the combined reagent-mixture stream, and a plurality of raised surface portions spaced relative to each other and projecting inwardly into the mixing chamber and transverse relative to its elongated direction for creating turbulence within the mixing chamber to facilitate mixing of the reagent-mixture components into the combined reagent-mixture stream; and

    means coupled in fluid communication with the outlet port for at least one of (i) chemically analyzing and (ii) analyzing a particle distribution of the combined reagent-mixture stream.
