Chromatographic Workstation is a computer system with the function of transforming analog signal collected in chromatogra-phy detector into digital signal, then making chromatographic peak discrimination and component analysis. Based on PCI8020 data ac-quisition card and multithreading this article implemented signal collecting and component analysis on four channel chromatography detector. Discussed spectra hump detection, area, height calculation, the display of chromatogram, component quantization. According to the analysis of test sample, a well-working system and the expected functions can be achieved completely.
