原子吸收光谱的LPDA波长分辨技术

Wavelength Resolution in AAS with LPDA Technigue

本文研究了用一维光电二极管阵列探测技术对石墨炉原子吸收光谱实现波长分辨的方法。所建立的LPDA-GFAAS实验装置光谱分布为0.014nm/diode。通过调节光源辐射强度及入射狭缝宽度、高度可避免LPDA电晕与饱和。

A method for wavelength resolution in GFAAS using LPDA detector is developed. The spectral distribution of the experimental system was 0.014nm/diode. The usability of LPDA in GFAAS was also discussed.
