ABSTRACT:
The present invention is directed to methods and apparatus for conducting gas chromatography more rapidly than previously disclosed. By means of the present invention the time necessary to conduct a gas chromatographic analysis can be reduced by more than 50%. The methods and apparatus employed reduce system dead volumes to prevent band broadening and mixing of the sample components as the gas sample is analyzed. The present invention also relates to the apparatus described above as applied to controlling chemical, refining, and other processes.
