Microvolume quench flow
Quench flow is the method for tracking kinetics of non-optically active solutions.
Typically two reagents are mixed, the mixture flows through a delay line at a defined flow rate to be aged and finally the reaction is stopped with a quencher.
QFM-4000 has been designed for working with microvolumes solutions as low as 10 µL and minimum manipulation. For example the instrument uses one single delay line of 3 µL and ageing times covered with this line ranges 3-4 ms to few seconds without rearrangement!
