The device comprises a first helium inlet, a first valve, a first water trap, a second helium inlet, a second valve, a second water trap, a third water trap, a temperature control heating furnace, a six-way valve, a carbon dioxide trap, a single-opening quartz tube, a carbon dioxide collecting tube, a liquid nitrogen cup, a stable isotope mass spectrometer, a sample injection needle, a sample tube and a plurality of connecting pipelines. A continuous flow sampling device is adopted, a mineral inclusion bursting device and the carbon dioxide collecting device are connected with the stable isotope mass spectrometer, and online heating bursting of the mineral inclusion, online collecting of carbon dioxide gas and online testing of carbon dioxide carbon isotope are achieved.

Description

technical field [0001] The invention belongs to the technical field of measuring the carbon isotope composition of carbon dioxide in mineral inclusions, and in particular relates to a measuring device and method for the carbon isotope composition of carbon dioxide in mineral inclusions. Background technique [0002] At present, the more mature methods for testing carbon dioxide in mineral inclusions are mainly off-line two-way method, which can be divided into vacuum ball milling method, crushing method, traditional burst method and improved sealed quartz tube burst method, but the two-way method has high sample preparation costs , low efficiency, large sample volume, large error and other shortcomings. [0003] The vacuum ball milling method is generally to put the purified and dried 40-60 mesh sample into the ball mill, vacuumize after sealing, grind the sample to open the mineral inclusions, collect the released carbon dioxide gas, and then use the two-way method to test ...
