基于脉冲采样的离子迁移谱仪装置
摘要：
本公开的实施例提供一种基于脉冲采样的离子迁移谱仪装置。离子迁移谱仪装置包括：离子迁移谱仪，配置用于检测样品；采样装置，配置用以采集样品并输出包含样品的混合气体；以及循环气路，配置成将采样装置与所述离子迁移谱仪流体连通，以便将采样装置输出的包含样品的混合气体导入至所述离子迁移谱仪，并且能够将离子迁移谱仪排出的气体的至少部分送回至所述离子迁移谱仪和/或所述采样装置。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The embodiment of the utility model provides an ion mobility spectrometer device based on pulse sampling. The ion mobility spectrometer apparatus includes: an ion mobility spectrometer configured to detect a sample; the sampling device is configured to collect a sample and output mixed gas containing the sample; and the circulating gas path is configured to enable the sampling device to be in fluid communication with the ion mobility spectrometer, so that mixed gas which is output by the sampling device and contains a sample is guided into the ion mobility spectrometer, and at least part of gas exhausted by the ion mobility spectrometer can be sent back to the ion mobility spectrometer and/or the sampling device.
