Abstract
Stopped-flow reaction apparatus includes a dual drive syringe pump for pumping predetermined amounts of particles and reactants into a common reaction loop, the length of the latter, as well as the flow rate of the mixed solutions, determining the reaction time. The reacted solutions are then massively diluted, by means of a diluent supplied from another syringe pump, so as to freeze the state of reaction thereof and the diluted, non-reacting solution is then conducted to a continuous-flow, resistive particle counting apparatus.
Claims10
Stopped-flow, reaction apparatus for use in conjunction with continuous-flow resistive-particle counting apparatus, comprising:
- means for housing a predetermined amount of particles to be counted;
- means for housing a predetermined amount of a reactant;
- means for simultaneously injecting said particles and said reactant into a common reaction loop having a predetermined length, at a predetermined flow rate so as to facilitate reaction of said particles by said reactant;
- means for housing a diluent, the amount of said diluent relative to that of said particles and reactant being in the range of 70 - 500 :
- 1;
- means for injecting said diluent into said reaction loop so as to massively dilute the same and thereby stop the reaction;
- continuous-flow resistive particle counting apparatus;
- and
- means fluidically connecting said reaction loop to said counting apparatus so as to supply said non-reacting solution to said counting apparatus.
