当今的几种高性能分析技术都是基于将液体恒定且无脉冲地输送到执行分析的系统。例如，在流动注射分析（FIA）中，系统通常是混合装置，其中试剂和样品在进入检测器之前相遇并反应，以在线定量给定产物。场流分馏（FFF）又是一类单相分离技术，其性能基于场和垂直流与待分离样品的耦合相互作用。这两种技术以及许多高分辨率色谱系统都依赖于稳定的液流来获得最佳性能和所产生的分析信息的准确性。
Several of today's high-performance analytical techniques are based on the constant and pulse-free delivery of liquid to the system performing the analysis. In flow injection analysis (FIA), for example, the system is generally a mixing device where reagents and sample meet and react prior to entering a detector for on-line quantification of a given product. Field-flow fractionation (FFF), in turn, is a family of one-phase separation techniques whose performance is based on the coupled interactions of a field and a perpendicular flow with the sample to be separated. Both of these techniques, as well as many high-resolution chromatographic systems, depend on a steady liquid flow for optimal performance and for accuracy in the produced analytical information.
