Unsegmented-flow configurations,

One of the most valuable assets of flow-through (bio)chemical sensors is their compatibility with unsegmented-flow configurations, which endows them with major advantages over probe-type sensors including higher flexibility and automatability in addition to wider applicability to real rather than academic problems — the former are rarely addressed by using sensors. 

It should be noted that Figs 2.12-2.16 do not include every possible type of configuration, as shown in subsequent chapters. Rather, they provide an overview of the wide variety of on-line coupled flow-through sensors and continuous unsegmented-flow analytical configurations. 

The flow system is designed to permit different reagent streams to be successively added by confluence. This is the essence of segmented flow analysers and is inherent in unsegmented flow analysers designed in the confluent configuration.
