New methodologies for the rapid determination of amino acids by ion-exchange chromatography have presented the highly instrumented laboratory with a vast volume of data to be calculated. Various manual methods of calculation (height-width, absorbence or planimetry) are time consuming and cannot be used to maintain an efficient balance between increased production of information and finished data. Electronic digital integrators have helped to eliminate manual interpretation from the strip chart recordings, but manual calculation must still be performed to obtain the final data. The ideal system would eliminate all manual handling of the data. The following describes such a system used by this laboratory in conjunction with Spinco 120 C amino acid analyzer.
