ABSTRACT
A robotic-based solution sample preparation station has been developed for inductively coupled plasma atomic
emission spectrometry. It is an integrated system of RS-232 modules controlled by an IBM PC/AT. The modules
consist of a robot (Mitsubishi RM-501) an electronic laboratory balance, a microprocessor-controlled syringe solution
dispenser/diluter and an inductively coupled plasma atomic emission spectrometer. Taken as a group, these modules
allow the automatic preparation of solution samples for trace element analysis along with feedback of results for
optimal solution preparation and analysis. However, such a system has significance beyond simple automatic sample
preparation as it allows the development, implementation and comparison of different analytical methodologies. Some
methodologies that are compared include normal calibration curves, automated standard additions, an automated
successive approximation method and automated matrix effect recognition and compensation.
