  • Method and apparatus for sample injecting in gas chromatography
    Patent number: 6719826
    Abstract: A method and an apparatus for sample injection in gas chromatography increases the injecting volume of a sample, and can analyze any of high-boiling-point compounds, low-compounds boiling-point compounds, and compounds decomposed by heat. 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.

  • Method and apparatus for mass injection of sample
    Patent number: 6203597
    Abstract: To enable the mass injection of a sample in a gas chromatography and prevent occurrence of residue or decomposition of a desired constituent during analysis. The invention calls for providing the injection port with a liner, connecting the column and the liner to a press-fit, evaporating the solvent introduced into the liner, and discharging the evaporated solvent from a discharge port formed at the upper part of the liner.
