| 摘要 |
The invention relates to a gas sampling device comprising a probe for sampling gas, an exploiting device for exploiting the gases sampled, a pipe for transmitting the gases sampled by the probe to the exploiting device, and means for lowering the pressure of the gases sampled in the pipe, to lower the dew point of the gases sampled, the means for lowering the pressure comprising an expansion nozzle arranged in the probe and communicating with the pipe, and a suction device for sucking the gases sampled in the pipe through the exploiting device. Application of the invention to the analysis of hot gases loaded with water vapor. |
