CHROMATOGRAPHIC DEVICE AND METHOD OF FABRICATION AND CHROMATOGRAPHIC METHODS

摘要

A chromatographic device for use in multi-dimensional GC is described having a gas flow channel means having an inlet and an outlet, and including a first length of tube defining a first stage and a second length of tube defining a second stage; wherein each of the first length of tube defining a first stage and second length of tube defining a second stage is microfabricated in the plane of a planar substrate layer such that each length of tube comprises a bore defining a closed curve in cross section. A GC assembly further comprising modulator, injector and detector and a method of fabrication of device and assembly are described. A method of analysing multi-dimensional GC data is described.
