Abstract

The invention discloses a spectral measurement system with adjustable atmosphere conditions. The spectral measurement system mainly solves the problems that an existing spectral analysis instrument islimited in application range and cannot satisfy diversified measurement. The spectral measurement system comprises a central control unit, and a gas injection system, a vacuum optical analysis chamber, an analysis chamber vacuum acquisition unit, a detection light path system and a collection light path system which are connected with the central control unit by means of signal cables. By combining the vacuum system and the optical system, the spectral measurement system realizes selective adjustment and control of the atmosphere conditions of a measured object, can eliminate interference ofair to spectral analysis completely, satisfies the analysis of specific substances under the condition of requiring characteristic atmospheres, can be adapt to analysis of high-activity, toxic, radioactive or other harmful substances, enhances the measurement capability of the spectral measurement system, and expands the measurement application range, thereby being suitable for popularization andapplication.

Description

technical field [0001] The invention relates to the technical field of vacuum instruments and optical analysis instruments, in particular to a spectrum measurement system with adjustable atmosphere conditions. Background technique [0002] The spectral measurement system with adjustable atmosphere conditions can selectively adjust and control the atmosphere conditions of the measured object, so as to eliminate the measurement interference caused by the atmosphere, improve the measurement capability and expand the scope of application of the measurement. [0003] At present, various types of spectral analysis instruments (such as LIBS, Raman spectroscopy, infrared spectroscopy, etc.) mainly use direct measurement in the atmosphere, measurement using inert gas purging, and measurement in transparent containers such as quartz for analysis and detection. In special application scenarios where the air interferes strongly with the measurement and the sample has high activity, toxi...
