Efficient and Rapid Chromatography for Various Gas Composition
气相色谱法高效快速分析多种燃气组分

The method introduced in this paper realizes full analysis of main components of synthetic gas and liquefied petroleum gas with single sampling for the first time under the comparatively ideal operation condition. This method used thermal conductivity detector, combination of three columns (pink support 6201 coated with stationary liquids, GDS 502 and 5A molecular sieve respectively) and multi dimensional column switching system. In comparing with conventional gas analytical methods based on chemical absorption and water flow calorimetry which are used as a test standard of gases, this method has the advantages of simple operation, quick response, good separation and satisfactory results. It solves the problem of efficient and quick analysis of multi component gases.
