摘要

Internal coupling of injection valves to establish several zones of reaction in non-segmented flow analyzers, in which an injection unit composed of two rotating valves of four ways connected so that the channel of entrance to the loop of sample of the first valve (1) it is connected to the carrier of dissolution carrier of the second valve (2) and the channel of exit of the loop of sample of the valve (1) to the departure of dissolution carrier of the valve (2). By entering a flow system, the sample fills the loop included between (1 and 2), while, the carrier dissolution and the loop (2) contains the reagent for the analysis. A mechanical actuation allows two valves to rotate simultaneously. M (Machine-translation by Google Translate, not legally binding)
