“…in tethered buoys, as described by Répécaud et al [240]. There has been limited, but continuing development of FIA in submersible systems and on remotely operated vehicles (ROVs) [128][129][130][131]180,[241][242][243][244][245][246], and there is great potential in this area, given the developments in microfluidic devices during the last decade. The microfluidic flow device described by Beaton et al for the determination of nitrate [247] is an example of the new generation of flow analysis devices under development.…”
