摘要： This invention relates to a device for vaporization injection in a gas chromatographic column housed in an oven. In order to avoid the drawbacks and problems arising with known vaporization injection techniques above all with samples with solvents, the device comprises a direct on column injector suitable for injecting the liquid sample into the initial zone of a capillary column and capable of pneumatically sealing the injection port at the end of injection: between the injector and the gas chromatographic column itself a capillary column length is provided in which vaporization of the injected sample occurs by heating an oven housing said capillary column length, said oven being the same or separate from the oven containing said gas chromatographic column.

摘要： A microwave heating apparatus (180) is used for heating a chromatographic column assembly (130) containing a microwave absorbing material. The microwave heating apparatus (180) includes an antenna (230) transmitting a microwave signal and a resonant cavity (240) containing the chromatographic column assembly (130) and the antenna (230). The chromatographic column assembly (130) extends relative to predetermined electromagnetic field strength contours within the resonant cavity to provide a predetermined heating profile along the length of the chromatographic column assembly (130). For example, a single-mode chromatographic column microwave oven can be used to heat a coiled chromatography column to a desired temperature gradient along its length. Oven design embodiments utilizing coaxial transmission line structures, coaxial resonators, and cylindrical resonators are described. To control the electromagnetic field gradient in the axial direction, the oven designs provide for varying some part of the oven geometry in the axial direction. For best operation, vacuum conditions should be established within the oven (180) during heating cycles.

摘要： To expedite breath gas analysis using gas chromatography, a sample from a patient is passed to two columns (51,52) maintained under different chromatographic conditions eg. low and high temperature. The effluent from both columns is then passed to a detector (53). In this way components such as acetone and 4-heptanone which have very different retention times on a single column, can be determined efficiently in a short time without deterioration of chromatographic resolution. The system is used in clinical analysis.
