GAS CHROMATOGRAPHY SYSTEM AND METHOD

摘要

The invention relates to a gas chromatography system for the direct coupling of liquid chromatography and gas chromatography or for the introduction of large sample volumes configured to work selectively in a retaining mode, comprising a tube (2) with a first inlet part (21) and a second inlet part (22), with a retaining part (3) located between the inlet parts. There are also two gas supply subsystems (6, 7), a sample introduction duct (101) connected to said first inlet part (21) and, connected to the second inlet part (22), an evacuation duct (9) and a gas chromatography column (300). The invention also relates to a gas chromatography method.
