Abstract

A simple X-ray fluorescence (XRF) analysis method has been developed for the determination of trace element concentrations in hair. It utilises strands of hair which are dropped on a Formvar foil and irradiated in an X-ray beam. The effective sample mass was estimated by measuring scattered X-ray photons. The attenuation correction for the X-rays from light elements was estimated using a simple model. Results are in agreement with those obtained by the atomic absorption method.

摘要

已开发出一种简单的X射线荧光(XRF)分析方法,用于测定头发中的微量元素浓度。该方法利用掉落在福尔马膜箔上的发丝,并在X射线束中进行照射。通过测量散射的X射线光子来估算有效样品质量。使用一个简单模型估算了来自轻元素的X射线的衰减校正。结果与原子吸收法获得的结果一致。
