Method and apparatus for sample injecting in gas chromatography

摘要

To provide a method and an apparatus for sample injection in gas chromatography that can significantly increase the injecting volume of a sample, and can analyze any of high-boiling-point compounds, low-boiling-point compounds, and compounds decomposed by heat at a high accuracy. A sample is injected into a vaporizing chamber 6 having curved or crooked outer wall 6G and sample path S and formed of continuous inner walls 6H; the sample is temporarily held in the vaporizing chamber 6; then an objective compound is vaporized, and introduced into a separation column 17.
