Intermittent Pumping and Merging Zones

A and B), Because the first pump is started (and the second one stopped) only when the next sample is being injected, this approach allows an increase in sampling frequency and saves reagent solution. A review article, demonstrating applications of the intermittent pumping procedure for various practical analytical tasks, has recently been published by Krug et al. [1060]. [Pg.174]
