荧光池与一般吸收光谱仪器的吸收池(比色皿) 不同。吸收池有两个透光面,而荧光池有四个透光面。其配对误差与内部几何尺寸,四个透光面的厚度、材质的均匀性及四个透光面的平面性、平行性等因素有关,故它比一般吸收池的配对误差更难控制。所以,荧光池配对误差的指标比一般吸收池稍大一些。检定用标准荧光池配对误 Fluorescent cells and general absorption spectrometer absorption cell (cuvettes) different. The absorption cell has two translucent surfaces, while the cell has four translucent surfaces. The matching error is related to the internal geometry, the thickness of the four translucent surfaces, the uniformity of the material and the planarity and parallelism of the four translucent surfaces. Therefore, it is more difficult to control than the matching error of a general absorption cell. Therefore, the error of the fluorescence cell matching index slightly larger than the average absorption cell. Calibration with the standard fluorescence pool matching error
