    Computer-controlled apparatus for automated development of continuous flow methods
    (1989) Wentzell, Peter D; Hatton, Michael J; Shiundu, Paul M; Ree, Ronald M; Wade, Adrian P
    An automated apparatus to assist in the development ofanalytical continuous flow methods is described. The system is capable of controlling and monitoring a variety ofpumps, valves, and detectors through an IBM PC-AT compatible computer. System components consist of two types ofperistaltic pumps (including a multiplepump unit), syringepumps, electrically andpneumatically actuated valves, and an assortment of spectrophotometric and electrochemical detectors. Details ofthe interface circuitry are given where appropriate. To demonstrate the utility of the system, an automatically generated response surface is presentedfor theflow injection determination of iron(II) by its reaction with 1,10-phenanthroline.
