[0029] The following is a further description of the present invention, rather than a limitation of the present invention.
[0030] In order to improve the spatial resolution of the “water” content analysis of nominally anhydrous minerals, realize the analysis of the “water” content of zircon minerals by large-scale magnetic mass spectrometry, in order to obtain more abundant geochemical information in zircons, the method in this disclosure It is based on the large-scale secondary ion mass spectrometer CAMECA IMS 1280-HR to simultaneously analyze the "water" content and oxygen isotope in zircon.
[0031] The selected single minerals ZG2, ZG3, ZG4, and 91500 were used as standard samples, and Penglai, Qinghu and Plesovices were used as samples to stick them on the double-sided adhesive tape in order, and the sample target (diameter 25.4mm, thickness 5mm.
[0032] The method of making the sample target can refer to the following steps:
[0033]Paste the double-sided tape on th...
