Abstract

The invention discloses a multi-path independent gas inlet system. The system comprises a gas path rack and a gas path mechanism fixedly arranged on the gas path rack; the gas path mechanism comprisesa gas path main pipeline communicating with external experimental equipment and comprises a plurality of gas inlet branch pipelines which communicate with the gas path main pipeline and are used forstoring and conveying samples to be injected; the plurality of gas inlet branch pipelines are mutually independent; the gas path main pipeline is also in pipeline connection with a vacuum pump set used for realizing pipeline vacuumizing; and the vacuum pump set is fixedly arranged on the gas path rack. The multi-path independent gas inlet system can be used to conveniently prepare high-purity gasor liquid samples, switching operation can be quickly performed, and inconvenience caused by frequent sample change in a use process of existing equipment is avoided.

Description

technical field [0001] The invention relates to an air intake system, in particular to a multi-channel independent air intake system used in scientific experiments in an ultra-high vacuum environment, and belongs to the field of vacuum scientific research equipment. Background technique [0002] The ultra-high vacuum equipment system is an indispensable and important hardware foundation for ultra-high vacuum experiments. It is generally composed of vacuum pumps, vacuum gauges, vacuum chambers and other components with the help of vacuum pipelines, combined according to certain requirements. To ensure that a specific vacuum environment is obtained and maintained in a certain space, and to ensure that a certain process or physical process is implemented in a vacuum system, it has a wide range of research fields in semiconductors, mechanical processing, physics, chemistry, materials and biological sciences. application. [0003] Specifically, in the course of a scientific expe...
