Software for Microprocessor Controlled HPLC: Data Acquisition and Display

Abstract

Programs are described for the direct computer-assisted acquisition and display of chromatographic data from conventional Hplc equipment. The programs are written for a dual-microprccessor Hplc controller and provide the necessary utility routine, to calibrate the instruments, and to acquire, display, and store chromatographic data in real-time. The data acquisition routines use data filtering techniques suitable for real-time data acquisition which remove spurious noise and ripple associated with detector analog outputs. The results of chromatographies indicate only negligible differences between d a t a acquired via the coniputer equipment and data acquired directly from Hplc detectors. The stored data can be retrieved for further computer-assisted analysis.
