Abstract

The invention relates to a sample transfer device and a sample transfer method. The device comprises a sample stage for placing a sample; a sealing cover which comprises a cover body covering the sample table and provided with a vent hole; and an elastic sealing suction assembly, wherein the vent hole of the sealing cover is elastically covered, and when the elastic sealing suction assembly is moved away from the vent hole, the vent hole can be communicated with the suction channel. The device has a positive and negative pressure transfer mode, is suitable for different sample transfer requirements, can reduce cost by one order of magnitude, and is more beneficial to popularization and application; for a common air sensitive sample, the trouble that vacuumizing equipment and other equipment need to be independently arranged is omitted, the air sensitive sample can be directly kept in vacuum, and the novel device can achieve good atmospheric environment isolation in the transfer process.

Description

technical field [0001] The invention relates to the technical field of photoelectron energy spectrum analysis, in particular to an air-sensitive sample transfer device and a transfer method of a photoelectron energy spectrum analyzer. Background technique [0002] X-ray Photoelectron Spectroscopy (XPS) is an energy spectrum technology based on the photoelectric effect. It uses soft X-rays of a certain energy to excite the inner electrons of the surface atoms of the material, and detects the kinetic energy and number of photoelectrons. In this way, the chemical state information and relative content of each element on the sample surface can be obtained. The conventional sampling method of the XPS instrument is to prepare the sample on the standard sample holder, and then transfer it to the sampling chamber of the instrument for pre-evacuation. During this process, the samples are exposed to the atmosphere and are sensitive to some air ( Such as easy to oxidize, easy to deliq...
