A new type of flow-injection procedure is proposed in which the samples are reversely pumped to the detector. In this procedure the injected samples are pumped into the reaction loop of a 6-way valve, then the valve is rotated to reverse the flow and the sample/reagent plug is pumped to the detector by another pump. The dispersion of the sample zone is low… CONTINUE READING
