Robotic system for analytical method development with on-line quantification and a graphical interface

Abstract

A robotic system that automates method development and performs simultaneous multiple-method, routine sample analysis was jointly developed between Rhône-Poulenc Agriculture Limited (RPAL) and Middlesex University. The system consists of 21 discrete workstations of varying complexity. Three different types were used: those that were ready to use and did not require modification, those that required modification, and those that were purpose-built. In order to achieve such a system, many of the discrete processes in the analytical laboratory were automated in separate work cells. A programmable logic controller and serial interfaces are used to control and communicate with a distributed controlling computer system. A small industrial robot mounted on a six meter length of track functions as a pick- and place-manipulator for the workstations. The control system gives the analyst full control of all the parameters associated with each workstation. A graphical user interface (GUI) allows analysts to use the system with minimal training and to graphically represent the process in a familiar form. © 1999 John Wiley & Sons, Inc.
