A newly developed geochemical sampler for fluids with high CO₂ concentration and at high temperature and for observation of rock-water interaction

Abstract

A new type geochemical probe was developed to collect fluids in deep depth (25 to 250°C) without flashing (gas-liquid separation) for accurate analyses of vapor concentrations such as CO₂ and simultaneously to monitor dissolution/precipitation phenomena of minerals such as carbonate and smectite during rock-water interaction.
