报告摘要

Standards were prepared in fused silica capillaries for the calibration of Raman systems for quantitative analyses of geological fluids, such as those found in fluid inclusions in minerals. The standards include fluids in unary (CH₄, CO₂), binary (CH₄-CO₂, CH₄-H₂O, CO₂-H₂O, CH₃COOH-H₂O) and ternary systems (CH₄-CO₂-N₂). Three different ways of standards preparation were introduced and compared. After calibrating the Raman spectroscopic system with some of these standards, it is credible to determine, for example, (1) the pressures of CH₄ in fluid samples, (2) the diffusion coefficient of CH₄ in water at room temperature, and (3) the solubility of methane hydrate in water. Fluid standards prepared in fused silica capillaries are reliable for calibration of Raman systems and small enough that they can be used for inter-laboratory comparisons.
