Patent ID: 11953409

Abstract:
A gas extraction device for metal mineral inclusions and a gas extraction method therefor are provided, the device includes a base plate, an annular carrier, sealing covers, a grinding assembly, a vacuum assembly, a gas-gathering assembly and a mass spectrometer. The annular carrier is disposed on the base plate, multiple grinding chambers are defined and evenly distributed in a circular shape on the annular carrier, the sealing covers are disposed at openings of the grinding chambers, the grinding assembly includes grinding hammers, and the grinding hammers penetrate through the sealing covers and extend into the grinding chambers. Side walls of each grinding chamber defines a first through hole and a second through hole. The vacuum assembly is communicated with the grinding chambers through the first through holes. The gas-gathering assembly is communicated with the grinding chambers through the second through holes. The mass spectrometer is communicated with the gas-gathering assembly.
