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.
Claims11
A method for mass injection of a sample, said method comprising the steps of:
- providing an injection port with a liner;
- connecting a column to said liner;
- evaporating a solvent introduced into said liner;
- and discharging the evaporated solvent from a discharge port associated with said liner.
A method for mass injection of a sample, said method comprising the steps of:
- providing an injection port with a liner;
- connecting a column to said liner;
- introducing a solvent and a sample into said liner and controlling the temperatures in said injection port and an oven in which said column is disposed so as to discharge evaporated solvent from a discharge port associated with said liner while accumulating and concentrating at least one constituent in said sample at the column.
An apparatus for mass injection of a sample, wherein an injection port having a body is provided with a liner;
- a column connected to the liner;
- the body of the injection port is provided with a split purge;
- and a discharge port for discharging vapor of evaporated solvent is formed at an upper part of the liner.
