Quench-Flow System

 

 

Quench-flow background

The chemical quench-flow method is used in transient-state kinetic analyses of reactions that cannot be monitored spectroscopically. In a typical experiment, reactants are allowed to age for a finite time, after which the reaction is terminated by addition of a chemical quench solution. The catalytic product is then analyzed by other methods (HPLC or mass spectrometry, for example), leading to determination of the kinetic parameters of the reaction.

KinTek RQF-3 quench-flow system

The KinTek RQF-3 stopped-flow system allows for characterization of kinetic reactions on a 2-100 millisecond time scale. The instrument utilizes a computer-controlled stepper motor and an 8-way reaction valve to achieve the desired reaction time. Temperature control is provided by a circulating water bath.
