Problems solved by technology

The more serious problem is that the use functions of related products imported from my country are greatly restricted, and flexible demand customization makes it difficult to better meet the needs of my country's scientific research industry
Therefore, the in-situ sample rod system imported from abroad with a single external environment is far from meeting the requirements of research work in most cases, which greatly limits the development of my country's in-situ observation technology field.
More importantly, this bought-in technology development method has caused my country's scientific research to lose its ability to conduct original exploration and experience accumulation. This is a great challenge for the development of a new generation of original scienti

Abstract

The invention discloses an optical sample rod system for an in-situ liquid and gas environment transmission electron microscope. The system comprises a sealed small sample table frame for manufacturing liquid and gas environments with different pressures in an ultrahigh vacuum environment, a hollow sample rod frame, a gas and liquid guide pipe arranged in the sample rod frame, an energy transmission optical fiber, a sealing rubber ring arranged in the small sample table frame and the like. A gas (liquid) environment exists in the sample rod head frame and is connected with external gas (liquid) inlet equipment through a gas (liquid) guide pipe. One end of the energy transmission optical fiber with the controllable wave band is fixed to the miniature sample table, and a main body of the energy transmission optical fiber extends out of a clamping groove in the miniature sample table, penetrates through the sample rod frame to be connected with an external light path unit and is used foradjusting the illumination environment in the miniature sample table. The system is suitable for exploring various physical and chemical life reaction processes such as gas-phase reaction, liquid-phase reaction, solid-phase and gas-phase interfaces, solid-phase and liquid-phase interfaces, photochemical reaction and the like.
