Patent ID: 8801979

Claim:
A continuous-flow injection reactor for synthesizing particles, comprising: a mixing zone unit comprising a) an outer housing comprising a top inlet, a bottom outlet, and a side inlet positioned between the top inlet and the bottom outlet, b) an injection tube inserted into the top inlet and positioned within the outer housing, the injection tube being of sufficient length to extend past the side inlet while terminating at about the lower edge of the side inlet and above the bottom outlet, and c) a mixing zone between a lower end of the injection tube and the bottom outlet of the mixing zone unit; a first fluid source providing a first reactant solution, operably coupled to the side inlet; a second fluid source providing a second reactant solution, operably coupled to the injection tube inserted into the top inlet; and a residence time unit, wherein the residence time unit has a diameter cooperatively dimensioned such that it can be removably coupled to the bottom outlet of the mixing zone unit.
