## Abstract In the present research, a split‐flow comprehensive 2‐D GC‐quadrupole MS (qMS) method was developed using: a primary apolar 30 m×0.25 mm id×0.25 μm __d__~__f__~ capillary linked, __via__ a T‐union, to a secondary polar 1.0 m×0.05 mm id×0.05 μm __d__~__f__~ capillary and to a 0.10 m×0.05

## Abstract A simple flow‐switching device has been designed for use as a comprehensive two‐dimensional gas chromatography modulator. The device is constructed from fused silica tubing, t‐unions, and a solenoid valve. A series of experiments were conducted to determine the influence of primary flow
## Abstract Many modulation systems in comprehensive 2D GC (GC×GC) are based on cryogenic methods. High trapping temperatures in these systems can result in ineffective trapping of the more volatile compounds, whilst temperatures that are too low can prevent efficient remobilisation of some compoun
