The flow system with fully rotary valve (FRV) operated as a directive valve has been designed and applied for calibration purposes. The role of the FRV was to create the set of standard solutions of compositions desired by directing and merging the streams of a single initial standard solution inser

✦ Synopsis
Design of the fully rotary valve (FRV) that has been developed in our laboratory as a part of a manifold of flow analysis is presented. It can serve as both a directive and an injection valve. In both versions, it can be used for various calibration purposes that can make analytical procedures simpler, faster, and more effective. In this report, some concepts are described that allow one to perform a single-component analysis with the use of a single standard solution.
