  • Method of geochemical characterization, production allocation, and monitoring using trace and ultra-trace element analysis
    Patent number: 11460408
    Abstract: A system for geochemical characterization of a sample includes a closed reaction chamber configured to perform a high temperature and high-pressure acid digestion test, a spectrometry system configured for performing trace element analysis, and a controller. The controller includes a processor and a memory. The memory includes instructions stored thereon, which, when executed by the processor, cause the system to mineralize the sample based on a microwave process using the closed reaction chamber, and perform trace element analysis on the mineralized sample by the spectrometry system.
    Type: Grant
