Optimization of a flow injection analysis system for multiple solvent extraction

Abstract

The performance of a multistage flow Injection analysis solvent extraction system has been optimized. The effect of solvent segmentation devices, extraction colls, and phase separators on performance characteristics is discussed. Theoretical consideration Is given to the effects and determination of dispersion and the extraction dynamics within both glass and Teflon extraction coils. The optimized system has a sample recovery similar to an Identical manual procedure and a 1.5% relative standard deviation between Injections. Sample throughput time is under 5 min. These characteristics represent significant Improvements over the performance of the same system before optimization. © 1982, American Chemical Society. All rights reserved.
