AI Technical Summary

Technical Problem

Existing technologies make it difficult to transfer solution samples to an ultra-high vacuum environment for high-resolution analysis without damaging their intrinsic properties, and existing methods also have compatibility and cleanliness issues.

Method used

A cryogenic solution sample preparation device was designed, including a sample preparation stage, a compressible linear introducer, a sample transfer chamber, a gate valve, and a vacuum pump. The solution sample is frozen on the sample collection device by a refrigeration device and then transferred and characterized in an ultra-high vacuum system, avoiding the heating and evaporation process.

Benefits of technology

It enables the high-purity transfer and characterization of solution samples in an ultra-high vacuum environment, preserving the original information, applicable to various solution systems, and safe transfer of unstable molecules, providing atomic-scale structural and compositional information.
