Abstract
Data acquisition is reported for a Varian CP 3800 gas chromatograph with affordable and user friendly interface box and software. LabPro was triggered to commence data acquisition upon sample injection and simultaneously monitored two detectors and oven temperature. After acquisition, functions are available for determining the retention time and for peak integration after baseline subtraction. Data may be exported as a text file. The interface box and software are available at a tenth of the cost of the instrument vendor's software. In this work, the determination of optimum carrier gas flow rate is reported as an example.
