Heater integrated gas chromatography column device

Abstract

A heater integrated gas chromatography (GC) column device according to the present invention is capable of precisely and uniformly controlling a temperature by having a high thermal conductivity, and raising and lowering a temperature at a high speed by having a low thermal mass, such that a measuring time is significantly decreased. The GC column is in contact with a bobbin with a homogeneous temperature distribution, and thus a temperature is homogeneously distributed in each GC column. Further, the heater integrated GC column device according to the present invention has the above-described effects and may have a smaller size.

Description

technical field [0001] The present invention relates to heater integrated gas chromatography (GC) column devices. Background technique [0002] In a general gas chromatography column (GC) device according to the related art, such as figure 1 As shown, the separation column is housed in a forced convection oven that forces convective air to reduce temperature distribution, thereby controlling the temperature of the separation column. Heating of the separation column by a forced convection oven is excellent in thermal uniformity and is less affected by ambient temperature. [0003] However, since the oven has a high thermal mass, it is not easy to control the heating and cooling speeds of the column, it is difficult to precisely adjust the temperature gradient, and the size of the device becomes very large, which is disadvantageous. In devices that include forced convection ovens, the response time required to raise or lower the temperature, ie to change the temperature to t...

AI Technical Summary

Problems solved by technology

[0003] However, due to the high thermal mass of the oven, it is not easy to control the heating rate and cooling rate of the column, it is difficult to precisely adjust the temperature gradient, and the size of the device becomes very large, which is disadvantageous

In units that include forced convection ovens, the response time required to raise or lower the temperature, i.e. the response time required to change the temperature to the set temperature, is long, which affects the time required to stabilize the set temperature

Therefore, the time required for analysis increases and the accuracy of analysis decreases
