摘要： A gas chromatographic chamber in the form of an oven is disclosed, including an outer envelope including insulated walls defining the chromatographic chamber which can be made air tight, an inner housing section within that chamber for housing the chromatographic column, and including an air distributor to maintain the uniform distribution of air within the inner housing section, as well as a heater to heat the air therein, non-thermally insulating partitions within the chamber and spaced from the insulated wall to provide a pneumatically insulated space between the insulated walls and the inner housing section, and a fluid circulator to create the controlled circulation of fluid within the pneumatically insulated space to effect the temperature within the inner housing section.

摘要： The invention relates to a modified-flame thermionic detector for gas chromatographs, of the type including a burner nozzle, an excitation electrode and a collecting electrode. The electrical connections of the nozzle and the excitation electrode can be changed at the operator's will, together with the spatial position of the excitation electrode with respect to the flame and the collector, to find out the presence of certain compounds, leaving all other conditions of analysis performance and detector supply unaltered. This allows obtaining chromatograms of unknown samples under different conditions of the detector configuration, to put into evidence the presence of certain compounds in the sample by comparing peaks of chromatograms obtained under said different operating conditions of the detector.

摘要： A method and apparatus for the quantitative determination of very small percentages of sulphur in sample analysis is carried out by means of sample combustion in a helium current temporarily enriched with oxygen, subsequent catalytic oxidation and reduction of the combustion gases, gas chromatographic separation and detection in a thermal conductivity detector. At the outlet of this thermal conductivity detector the products are fed to a water trap and to a sulphur selective detector of the flame photometric type to detect sulphur contents below 0.5 .mu.g.
