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

A robotic system that automates method development and performs simultaneou s multiple-method, routine sample analysis was jointly developed between Rh one-Poulenc Agriculture Limited (RPAL) and Middlesex University. The system consists of 21 discrete workstations of varying complexity. Three differen t types were used: those that were ready to use and did not require modific ation, those that required modification, and those that were purpose-built. In order to achieve such a system, many of the discrete processes in the a nalytical 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 mo unted on a six meter length of track functions as a pick- and place-manipul ator for the work stations. The control system gives the analyst full contr ol of all the parameters associated with each workstation. A graphical user interface (GUI) allows analysts to use the system with minimal training an d to graphically represent the process in a familiar form. (C) 1999 John Wi ley & Sons, Inc.
