Abstract
Abstract A method of and a robotic system for preparing product samples to be analyzed at a later time has a plurality of processing stations in different locations. Each station performs a different function of a process for preparing a product sample for later chemical analysis. A robot moves a first container between a container storage area and a prepared sample area for storing in a second container a product sample which has been prepared for analysis and in which the robot moves the first container from the container storage area to each of the processing stations in a predetermined sequence and then removes some of the prepared product sample from the first container and dispenses it into the second container which is located in the prepared sample area. A specific application of such a robotic sample preparation system is disclosed for use in preparing tobacco samples for analysis of nicotine and sugar content.
