Gravity Correlation and Separation Effect of Flow in HPLC

国际空间站项目的空间飞行任务实验的选择工作已经在许多相关国家使用降落塔和抛物线战斗机进行。我们研究了在有塔和飞机的空间中的分离过程。高效液相色谱分离过程是反应-扩散-流动系统中的现象，由于涉及的因素多而复杂，控制过程的实验条件必须由经验确定。但我们可以从理想状态的间隙的角度，将过程看作是在开放条件下运行的非平衡和化学现象。我们在JAMIC(日本微重力中心，龟川，北海道)的自由落体装置中，在微重力条件下进行了薄层色谱(TLC)的图案动力学实验。薄层色谱的原理与高效液相色谱柱的原理基本相同。爆炸的速度在微重力下增加，在超重力下减小。这与实验前的预期是一样的，它表明TLC中的膨胀是与引力背道而驰的。

The selection workings of the space-mission experiments on the International Space Station Project have been run with drop towers and parabolic fight airplanes in many related countries. We have studied the separation processes in the space with a tower and an airplane. The separation processes in a HPLC (high performance liquid chromatography) are phenomena in a reaction-diffusion-flow system and the experimental conditions must be empirically determined to control the processes because many and complex factor are related to them. But we can treat the processes as non-equilibrium and chemical phenomena running under an open condition from viewpoint of gap from a ideal condition. We have had experiments of the pattern dynamics in a TLC (thin layer chromatography) under a micro-gravity in a free-fall facility at JAMIC (Japan Microgravity Center, Kamisunagawa, Hokkaido). The principle of a TLC is as same as that of a HPLC essentially. The rate of the explosion increases as it is under a microgravity and decreases as under overgravity. These are as same as those expected before the experiment and it demonstrates that the expansion in a TLC runs against a gravity.
