Summary

Two variable volume injection valves, equipped with bypass loops, have been developed, primarily to circumvent problems with matrix effects in high sensitivity FIA.

The application of a dual channel valve for simultaneous analysis, zone sampling and merging zones techniques is discussed.

Examples for on-line dilutions up to several thousand-fold and the direct determination of calcium in Kjeldahl digests using the zone sampling approach and a study of the interference of ascorbic acid on the Griess reaction for nitrite are presented. The application of “chasing zones” techniques by coupling a simple single channel valve in a new way is proposed.
