Abstract: The present invention discloses a gas analyzing apparatus and a sampling device. The gas analyzing apparatus includes a sampling device and an ion mobility spectrum analysis device. The sampling device includes a multi-capillary column and a temperature control system. The ion mobility spectrum analysis device is adapted for analyzing a gas leaded-in by the sampling device and includes a reaction cavity for reaction between sample molecules and reaction ions, the cavity having a sampling opening for leading-in of the gas. An outlet end of the multi-capillary column is inserted directly into the cavity of the ion mobility spectrum analysis device through the sampling opening of the ion mobility spectrum analysis device.
