摘要
The invention relates to a method and device for direct non- vaporizing on column-injection of samples containing high boiling point and/or medium volatile compounds, in gas chromatographic analysis on capillary column. For reasons of economy, the oven containing the column is maintained at a temperature very mcuh higher than the boiling point of the solvent, while the initial part of the column (at least 10 cm) is cooled during the injection. The quantity of sample and solvent injected is related to the length of the cooled section of the column.
