研制了一种适用于熔氟盐和其他腐蚀性液体的新型无窗分光光度池。通过这种被称为俘获式液体电池的电池，光线通过一个垂直的液体柱的侧面传输，该液体柱被保存在一个特殊设计的金属圆柱形容器中。没有窗口材料或镜子是必要的细胞的操作。液体样品的路径长度与最初放置在细胞中的样品的重量或体积无关，但假定取决于液体的表面张力和密度。根据0.250英寸（0.635 cm）外径的吸光度测量，水溶液的路径长度为0.68；熔融共晶在540℃时的路径长度LiF—NaF—KF为0.77。这两个测量值的标准差都是±0.02厘米。该细胞用于熔氟盐的分光光度法研究。它也可用于其他腐蚀性溶液和液态熔盐的分光光度研究，温度可达1000℃以上。随着高强度单色光源（如激光）的出现，more»电池似乎非常适合拉曼光谱领域的使用。(身份验证)«更少
A new type of windowless spectrophotometric cell for use with molten fluoride salts and other corrosive liquids was developed. By means of this cell, called a captive liquid cell, light is transmitted through the side of a vertical column of liquid which is held in a metal cylindrical container of special design. No window material or mirrors are necessary to the operation of the cell. The path length of liquid samples held in this cell is independent of the weight, or volume, of sample initially placed in the cell but is postulated to be dependent on the surface tension and density of the liquid. Based on absorbance measurements in 0.250-inch (0.635-cm) OD cells, the path length of aqueous solutions is 0.68; the path length of the molten eutectic, LiF--NaF-- KF, at 540 deg C is 0.77. The standard deviation of both these measurements is plus or minus 0.02 cm. The cell was used for spectrophotometric studies of molten fluoride salts. It should also be useful for spectrophotometric studies of other corrosive solutions and molten salts in their liquid states up to temperatures well over 1000 deg C. With the advent of high intensity monochromatic light sources, such as lasers, themore » cell seems ideally suitable for use in the field of Raman spectrometry. (auth)« less
