Definitions
- Another object is to provide such a column having improved coupling between such column and the heat source.
- Another object is to provide such a' column wherein expansion of the heated column does not destroy the improved coupling.
- Another object is to provide such a column which may be rapidly cooled from its maximum temperature to a new starting temperature.

- FIG. 7 is a View taken along line 77 of FIG. 6;
- FIG. 8 is an elevational view showing the mechanical construction of the heater mounting device of this invention.
- FIG. 9 is an overall schematic view of a chromatographic apparatus embodying this invention.
- a column is wound so as to lie in a single plane and to allow the two ends of the column to be exposed without crossovers.
- Such a planar wound column is then mounted in direct contact with a plate-like heater.
- the column and heater may be maintained in close thermal contact by means of a suitable clamping mechanism.
- passages for air or other cooling fluid may be provided along the surfaces of the heater-column combination and suitable means may be provided for passing cooling fluid therethrough.
- FIGS. 6 and 7 The manner in which the column structure 11 of this invention is constructed will be best understood by reference to FIGS. 6 and 7.
- Two thin plates 10, 12 of a suitable heat conducting material such as aluminum are spot welded to opposite sides of a central core assembly made up of segments 14 and 16.
- the spacing provided between members 10 and 12 is such as to closely contact both sides of the chromatographic column 13 to be employed.
- Such a column may be either a Golay column or a packed column.
- the column is wound by passing approximately one-half the tube through the opening between spacers 14 and 16.
- the twoends of the column are then brought together and are spirally wound about the central core in the manner illustrated. It will be noted that the ends 18, 20 of the column may be brought out from the edge of the assembly without crossing over any previous turns.
- the heater employed with this column is constructed as shown in FIG. 4.
- the heater 24 is a solid aluminum disc.
- the disc is cast to include a suitable electrical heating element 26 wound in double spiral form as was the column.
- a temperature sensing wire 28 is also cast into the assembly between the double spiral turns. Heating element 26 and temperature sensor 28 are insulated electrically from the aluminum disc. Suitable metallic positioning spacers 30 retain the elements in proper alignment during the casting process.
- FIG. 3 A cross-section of a completed heater assembly is shown in FIG. 3. It will be seen that a base plate 32 is provided with a number of ceramic insulators 34 which are mechanically fastened thereto by wires 35 through the insulators and inserted into holes in plate 32. The function of these spacers is to provide air cooling passages for channeling cool air from inlet air duct 36.
- the heating element 24 may be hinged as shown in FIG. 8 wherein hinge 38 is of the type that provides a degree of freedom in the vertical direction. Heater 24 may be pivoted downward to the position shown in FIG. 3, where it rests upon the ceramic spacers 34.
- the completed column assembly llis placed directly upon the surface of heater 24.
- a cover plate 40 is then positioned over the column.
- Cover plate 40 carries upon its surface a number of ceramic spacers 42 identical to spacers 34 which similarly form passages for cooling fluid across the surface of column assembly 11.
- the top and bottom of the complete assembly are covered with rigid heat insulation 44.
- a clamp mechanism including a U strap 46 and a thumb screw 48 holds the assembly together and provides adequate pressure on the heater-column assembly to insure good thermal contact.
- Rapid cooling of the column of this invention is provided by cooling air duct 36 which receives air either from a blower 50 driven by a suitable motor 52 or from a compressed air supply 54.
- the housing for the heater- 3 column assembly may be of sheet metal provided with additional heat insulation 56 as required in addition to the rigid heat insulation 44.
- FIG. 9 illustrates the manner in which the column 13 is connected into a chromatographic system.
- carrier gas supply conduit 58 provides carrier flow to a heated injector block 60.
- the carrier gas flows' through block 60, past assembly injection point 62 where it picks up the sample to be analyzed.
- a suitable stream splitter 64 Upon reaching a suitable stream splitter 64 a portion of the carrier-sample combination passes into conduit 66. The remainder is vented through waste line 68.
- the samplecarrier combination in line 66 passes into inlet 18 of column 13 where separation occurs.
- Upon leaving column 13 the various components are separately eluted through line 20 and eventually pass to a suitable mixing T 70.
- Mixing T 70 mixes the elutant with a fuel gas, such as hydrogen, supplied from line 72.
- a fuel gas such as hydrogen
- the resulting mixture passes to a detector such as flame detector 74.
- the electrical signal from detector 74 is amplified by amplifier 76 and applied to a suitable recorder 78.
- Jumper 80 which is in the flow path between column 13 and mixing T 70, is provided in order that a second column may be easily inserted in series with column 13. This is accomplished by merely removing this jumper and connecting the second column inlet and outlet in its place. It will be understood that a detector of any suitable type may be used with this invention. The invention is not limited to use with a flame detector.
- the sensing wire 28 of the heater may be included in a bridge circuit for automatically programming the temperature of the assembly. In this way extremely accurate and linear temperature control is achieved. Furthermore, it
