• Description:
  The use of short columns and high carrier gas flow rates has been reported as a means of achieving separation of the components of mixtures in very short time periods. The recognition that optimal performance of short columns could only be achieved if injection plug widths approached a few milliseconds has led to a number of devices and studies aimed at achieving the goal of rapid sample introduction. Advances in this area in the past few years have included the use of high-speed mechanical valves or fluid logic gates. The use of cold trapping for the collection of airborne samples and the rapid reinjection of collected vapor or liquid samples has also resulted in the development and investigation of many effective systems. In a previous study in our laboratory, the design and performance of an electrically heated cold trap for high-speed gas chromatography was reported. In the present study, an improved low-voltage capacitive discharge power supply is combined with an electrically heated cold trap inlet and high-speed data collection and management system to obtain improved performance when compared to the previously reported system.
