Various analytical methods, including chromatography, microreactor etc, have been developed with ice and salt-doped ice as functional materials. We can, for example, detect 1000 magnesium ions confined in a liquid inclusion with a diameter of 1. m using salt-doped ice as a microreactor. This strongly suggests that sensitive analyses are possible with salt-doped ice as a platform for microreaction. These analytical studies have revealed that some reactions are remarkably facilitated in a liquid phase coexistent with ice. In addition, X-ray absorption fine structural analyses have revealed the difference in the hydration structure of ions between in bulk doped ice and on its surface.

以冰和掺盐冰为功能材料，发展了各种分析方法，包括色谱法、微反应器等。例如，我们可以检测到1000个镁离子被限制在直径为1的液体包裹体中。我用掺盐的冰作为微反应器。这有力地表明，灵敏的分析是可能的，与盐掺杂的冰作为一个平台的微量反应。这些分析研究表明，在与冰共存的液相中，某些反应会得到显著的促进。此外，X-射线吸收精细结构分析揭示了掺杂冰中离子水合结构与其表面离子水合结构的差异。
