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.
