Computer-controlled apparatus for automated development of continuous flow methods

摘要

An automated apparatus to assist in the development of analyticalcontinuous flow methods is described. The system is capable ofcontrolling and monitoring a variety of pumps, valves, anddetectors through an IBM PC-AT compatible computer. Systemcomponents consist of two types of peristaltic pumps (including amultiple pump unit), syringe pumps, electrically and pneumaticallyactuated valves, and an assortment of spectrophotometric andelectrochemical detectors. Details of the interface circuitry are givenwhere appropriate. To demonstrate the utility of the system, anautomatically generated response surface is presented for the flowinjection determination of iron(II) by its reaction with1,10-phenanthroline.
