| Abstract | A gas analyzer having a compact and simple structure and having a high performance in separating components of a sample gas is provided. The gas analyzer according to the present invention includes a gas introduction unit including a gas introduction port for introducing a sample gas; a gas separation unit including a microcolumn for separating components of the sample gas supplied from the gas introduction unit; and a gas detection unit detecting a gas component separated by the gas separation unit. The microcolumn is provided with an internal channel having a wall surface modified by a stationary phase. This stationary phase is made of a polar material having a relative permittivity of not less than 10 at 30° C. |
