掺杂气发生装置
摘要：
本发明涉及一种为离子迁移谱仪提供反应气的掺杂气发生装置，包括：掺杂罐；进气管，所述进气管的进口端与载气气路的上游侧连接，其出口端与掺杂罐连接；出气管，所述出气管的进口端与掺杂罐连接，其出口端与载气气路的下游侧连接；掺杂气发生单元，其用于释放掺杂剂气体，其中掺杂气发生单元置于所述掺杂罐中；所述掺杂罐的下端设置有可拆卸地连接到掺杂罐上的底盖，所述底盖上设置有固定所述掺杂气发生单元的支架。通过将用于释放掺杂气体的掺杂气发生单元置于所述掺杂罐中，本发明的掺杂气不仅可用固态掺杂剂，也可以用于液态掺杂剂。
摘要（英）：

The invention relates to a dopant gas generating device. The dopant gas generating device is utilized for providing reaction gas for an ion mobility spectrometer. The dopant gas generating device comprises a doping tank, a gas inlet pipe, wherein an inlet end of the gas inlet pipe is connected to an upstream side of a gas carrying passage and an outlet end of the gas inlet pipe is connected to the doping tank, an gas outlet pipe, wherein an inlet end of the gas outlet pipe is connected to the doping tank and an outlet end of the gas outlet pipe is connected to a downstream side of the gas carrying passage, a dopant gas generating unit, wherein the dopant gas generating unit is utilized for releasing dopant gas and is arranged in the doping tank, and a bottom cover, wherein the bottom cover is removably connected to a lower end of the doping tank and is provided with a support for fixing the dopant gas generating unit. The dopant gas generating unit for releasing dopant gas is arranged in the doping tank and thus the dopant gas generating device is suitable for a solid doping agent and a liquid doping agent.
