Definitions
- the present invention relates to a gas chromatograph apparatus provided with a sample introduction part, a separation column, and a detector.
- a gas chromatograph generally includes a gas introduction unit for introducing a sample gas, a separation column for separating the sample gas into components, a detector for detecting the separated sample components, and an oven.
- a gas introduction unit for introducing a sample gas
- a separation column for separating the sample gas into components
- a detector for detecting the separated sample components
- an oven In the oven, together with the separation column, piping connecting between the sample introduction part and the separation column and piping connecting between the separation column and the detector were accommodated and their temperatures were adjusted.
- the oven includes a heater and a fan, and is a heat convection type oven that uniformly heats the inside of the oven by circulating air heated by the heater.
- a sample introduction part 60 and a detector 64 are attached to the upper part of the oven 74, and inside the oven 74, a capillary 66 for connecting the sample introduction part 60 and the separation column 62 is accommodated in addition to the separation column 62.
- the capillary 66 is provided with a coiled portion 68, and the coiled portion 68 constitutes a guard column or a retention gap.
- the guard column is inserted between the sample introduction part and the separation column for the purpose of preventing the separation column from being contaminated by impurities and high-boiling components.
- the guard column may or may not have a liquid phase, but it is said that the channel length is required to be about 0.5 to 5 m.
- the guard column must be replaced or partially cut depending on the degree of contamination.
- Retention gap refers to sample introduction in order to prevent the spread of peak components and splitting of one component peak caused by the large amount of sample injection when the on-column method or splitless method is used as the sample introduction method. Is inserted between the column and the separation column.
- the capillary as the retention gap needs to be an inactivated capillary that is not coated with a liquid phase, and the channel length is generally required to be about 0.5 to 5 m.
- the problems with the above gas chromatograph device include the slow heating and cooling speed of the separation column and the power consumption due to the heat capacity of the heat convection oven.
- Patent Document since the separation column is housed in a separate container with a heating wire wound and disposed outside the oven as a column module, the heat capacity of the heating target is reduced, and the separation column is heated at a high speed. This makes it possible to improve the temperature control response of the separation column and reduce the power consumption for raising and lowering the temperature of the separation column.
- a transfer line connecting the sample introduction part and the separation column or between the separation column and the detector is installed in the oven. It is necessary to adjust the temperature separately from the separation column, and there is a limit to reducing the power consumption due to the presence of the heat convection oven. Further, when a guard column or a retention gap is inserted between the sample introduction part and the separation column, they are accommodated in a thermal convection oven.
- the effective temperature rise rate is determined by the temperature rise rate of the heat convection oven, and the temperature is adjusted compared to when the separation column is housed in the heat convection oven It is difficult to say that the improvement of the responsiveness and the reduction of power consumption are achieved.
- a separation column chip for example, a plate in which a channel is formed by bonding silicon and glass with a groove formed

Then, by removing a part of the jacket, it is possible to perform a treatment such as replacement of the guard column or the retention gap or partial cutting.
- the temperature difference between the jacket contact portion and the non-contact portion of the capillary becomes significant. It is necessary to secure a wide space. For this reason, there is a limit in reducing the space inside the jacket, and there is a limit in improving the heating rate of the capillary.
- an object of the present invention is to improve the temperature control responsiveness of the separation column and transfer line and reduce the power consumption required for raising and lowering the temperature of the separation column.
- a gas chromatograph apparatus includes a sample introduction unit, a detector, a separation column, a transfer line connecting the sample introduction unit and the separation column, and between the sample introduction unit and the detector, and a separation column.
