Abstract
Abstract A METHOD FOR CORRECTING FOR INTERACTION BETWEEN SUCCESSIVE FLUID SAMPLES IN CONTINUOUS FLOW ANALYSIS COMPRISES ANALYZING A SERIES OF FLUID STANDARDS, TWO OF WHICH ARE IDENTICAL. THE STANDARDS ARE ANALYZED IN ANY ORDER IN WHICH ONE OF THE IDENTICAL STANDARDS IS PREDEDED BY A STANDARD OF HIGHER CONCENTRATIONAL VALUE AND THE OTHER IS PRECEDED BY A STANDARD OF LOWER CONCENTRATIONAL VALUE. ANALYSIS OF THE ANALYTICAL RESULTS BY A REITERATIVE ESTIMATION PROCEDURE PROVIDES AN ACCURATE ESTIMATE OF INTERACTION AND A CALIBRATION CURVE CORRECTED FOR INTERACTION. THESE CAN BE USED TO PROVIDE ANALYTICAL SAMPLE DATA CORRECTED FOR INTERACTION.
