摘要

石墨炉原子吸收光谱法(GFAAS)是一种灵敏度高、样品体积小的测定样品中元素的方法。在电热加热的雾化器中，分析物在高温下转化为原子。尽管线源GFAAS仍在广泛应用，但高分辨率连续源(HR-CS) GFAAS对基体诱导的光谱背景提供了更精确的校正。本文回顾了GFAAS的最新创新和发展，包括仪器;基本性质的表征;HR-CS GFAAS研究进展;样品制备程序，包括蒸汽产生，固体和泥浆取样;基本形成;预选/分离协议;直接分析。结论部分总结了GFAAS的主要研究进展和未来发展方向。

Innovations and developments in graphite furnace atomic absorption spectrometry (GFAAS)

Abstract Graphite furnace atomic absorption spectrometry (GFAAS) is a highly sensitive method for the determination of elements in samples while requiring a low sample volume. The analytes are converted to atoms at high temperatures in an electrothermally heated atomizer. Although line-source GFAAS continues to widely employed, high-resolution continuum source (HR-CS) GFAAS offers more accurate correction for matrix-induced spectral backgrounds. This article reviews recent innovations and developments in GFAAS, including instrumentation; the characterization of fundamental properties; progress in HR-CS GFAAS; sample preparation procedures including vapor generation, solid, and slurry sampling; elemental speciation; preconcentration/separation protocols; and direct analysis. The conclusion summarizes major developments and future directions in GFAAS.
