Abstract
A separation column for analyzing a gas includes a capillary which is filled with a separation material. In order to be able to use the separation column in a microsystem technology, spheres are used as the separation material. The spheres all have the same diameter. The diameters of the spheres are slightly smaller than the internal diameter of the capillary or are matched to the internal diameter of the capillary. The spheres are provided inside the capillary in a row one behind the other.
Claims10
A separation column for analyzing gases, comprising:
- a capillary having an inner diameter being substantially 200 μm;
- spheres having substantially identical diameters, said spheres being disposed as a separation material in said capillary, said substantially identical diameters of said spheres being between 150 vim and 200 μm.
A separation column for analyzing gases, comprising:
- a capillary having an inner diameter;
- spheres having substantially identical diameters, said spheres being disposed as a separation material in said capillary, said spheres having respective center points, said spheres being disposed inside said capillary such that all of said center points of said spheres are provided along a straight line;
- each of said substantially identical diameters of said spheres being selected from the group consisting of a diameter matched to said inner diameter of said capillary and a diameter marginally smaller than said inner diameter of said capillary.
