Flow calibration system with the use of fully rotary directive valve

摘要

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 inserted into a flow manifold. The idea is presented of how different numbers of standards with the analyte concentrations distributed variously along a calibration line are possible to be prepared. It has been experimentally revealed that the system developed allows one to perform the calibration procedure with low consumption of time, work, and reagents, providing accurate and precise analytical results. © 1999 John Wiley & Sons, Inc.
