Cryo-electron microscope sample transfer system, method, electronic equipment

Abstract

The invention belongs to the technical field of scanning electron microscopy, and specifically relates to a cryo-electron microscope sample transfer system, method, and electronic equipment, aiming to solve the problem that the cryo-electron microscope sample changes during the transfer process; the system includes a master control center, a transfer table base, a transfer device, transmission rod, moving device, rotating device and vacuum docking mechanism; The second power device and the second transmission assembly; the moving assembly composed of the moving slider, the limit slider and the transmission rod moves to the transmission rod and connects with the transfer device, and the limit slider is locked with the second transmission assembly; the transmission rod, the limit slider The rotary assembly composed of the position slider and the second transmission assembly is rotated until the transmission rod is locked with the transfer device; the transfer device and the moving assembly are moved to the vacuum docking mechanism; the invention effectively prevents the structure and properties of the sample from changing during the transfer process.

Description

technical field [0001] The invention belongs to the technical field of scanning electron microscopes, and in particular relates to a cryo-electron microscope sample transfer system, method and electronic equipment. Background technique [0002] The sample room of the conventional scanning electron microscope is a high vacuum environment, which requires the observation sample to be dry and non-volatile. However, many samples contain water, oil or are volatile, so they cannot meet the conditions of the conventional electron microscope. At the same time, the loss of water and oil will also cause sample structure, The nature changes and the test data is distorted. The cryo-scanning electron microscope developed in recent years makes it possible to observe natural gas hydrates, oil-bearing rocks, biological cells, suspensions, hydrogels and other water-containing and oil-containing samples that cannot be observed by conventional electron microscopes with the help of ultra-low tem...
