Abstract

The use of an inexpensive analog-to-digital converter for interfacing gas chromatographs to computers in a teaching laboratory environment is described. Raw data may be read, processed, and printed from software supplied with the converter to afford chromatograms of acceptable quality. Alternatively, data may be imported into readily available commercial spreadsheet programs, which allows for easy analysis and production of more attractive chromatograms.
