Summary

A method is described for processing in a computer the chromatogram obtained when a given mixture, e.g., in a continuously flowing sample stream, is introduced into the column in a continuous series of square waves. The method involves the construction of an estimate of the output chromatogram based on an estimate of the parameters of the equivalent impulse chromatogram, and the iterative improvement of the estimate by non-linear regression analysis. The method is shown to yield results with a repeatability of 0.2 to 0.3% for a simple mixture, and is more economical in computer space and time than general cross-correlation procedures.
