Abstract

Several different analytical systems are available for biomedical elemental analysis related to human nutrition. The principle, detection limits, analytical artifacts, and applications are presented for the following analytical systems for elemental analysis classified by sample volume: macro volume systems--flame atomic absorption spectroscopy (FAAS) and inductively coupled plasma (ICP); micro volume systems--electrothermal atomization (graphite furnace) atomic absorption spectroscopy (ETA-AAS) and x-ray fluorescence (XRF); and ultramicro volume systems--electron probe x-ray microanalysis (EPX) and laser microprobe mass analysis (LAMMA).

摘要

有几种不同的分析系统可用于与人类营养相关的生物医学元素分析。本文介绍了以下按样品体积分类的元素分析系统的原理、检测限、分析假象和应用：大量系统——火焰原子吸收光谱法（FAAS）和电感耦合等离子体（ICP）；微量系统——电热雾化（石墨炉）原子吸收光谱法（ETA-AAS）和X射线荧光光谱法（XRF）；以及超微量系统——电子探针X射线微分析法（EPX）和激光微探针质谱分析法（LAMMA）。
