Introduction

During the implementation of my country's lunar exploration project, the National Astronomical Observatory of the Chinese Academy of Sciences was responsible for the construction of the lunar sample laboratory. The work of ground sampling, preservation, preparation and research was carried out, forming a method for sampling and long-term preservation of lunar samples in a high-purity nitrogen environment on the ground. ability. This document is compiled to review the laboratory storage, sampling, processing, and preparation of lunar samples that have been carried out in combination with the scientific goals of my country's lunar exploration project. The research contents of the lunar sample preparation and analysis are summarized, and a series of research projects on lunar sample sorting and analysis are formed by drawing on the experience of building lunar sample laboratories abroad. The preservation methods and requirements are expected to be used for future lunar samples in my country, as well as subsequent samples from asteroids, Mars and other extraterrestrial bodies. The sampling and preservation process can be guided and referenced. Lunar sampling sample separation and storage requirements
