我们已经开发了一种紧凑的尺寸高温高压光学池，可以安装在商业上可用的通用光谱仪。一个小电炉加热高压光学池，而水冷热屏蔽夹套保护光谱仪。这种冷却装置非常有效地消除了光谱仪光学器件的不希望的加热，因此可以在高达600 °C的温度下使用普通光谱仪进行光谱测量。 光学元件由Hastelloy-X制成，并配备了两个合成蓝宝石光学窗口。光路的长度和直径分别为10 mm和6 mm。由于光学池与流动系统相结合，可以快速用参考水替换样品溶液，因此可以在测量样品信号后立即获取参考信号。所开发的电池可以在高达60 MPa和600 °C的温度下运行，而无需对光谱仪进行任何特殊修改。 NiBr...
We have developed a compact size high-temperature high-pressure optical cell that can be mounted on a commercially available general-purpose spectrometer. A small electric furnace heats the high-pressure optical cell while a water-cooled thermal shielding jacket protects the spectrometer. This cooling device works quite effectively to eliminate undesirable heating of spectrometer optics and thus makes it possible to take spectra at temperatures up to 600 °C with an ordinary spectrometer. The optical cell is made of Hastelloy-X and equipped with two optical windows of synthetic sapphire. The length and the diameter of the optical path are 10 and 6 mm, respectively. As the optical cell is combined with a flow system, which allows the quick replacement of the sample solution with the reference water, the reference signal can be taken immediately after the measurement of the sample signal. The developed cell can be operated up to 60 MPa and 600 °C without any special modification to the spectrometer. The NiBr...
