塞曼汞光谱仪RA-915+适用于空气、水、土壤、食品、煤炭、石油等多种样品中汞含量的直接测定(无需吸收捕集预富集步骤)，具有背景水平检测限。同一RA-915+光谱仪使用不同的附件将结合态汞转化为原子形式，以测定复杂基质样品(全血、头发、原油、植物、食品)中的汞浓度，研制了双室热解原子化器。它的设计允许分离汞化合物的蒸发和解离过程，并实时简化气相中的基质成分。文中给出了简单和复杂矩阵样品的分析结果。(C)2004爱思唯尔B.V.保留所有权利。
Zeeman mercury spectrometer RA-915+ is suitable for the direct determination (without the preconcentration step in the absorption trap) of mercury concentrations in various samples, such as air, water, soil, food, coal, oil and so on with background levels detection limits. The mercury concentrations were determined by the same RA-915+ spectrometer using different attachments to convert bound mercury to its atomic form, To determine mercury concentrations in samples with complex matrix without pre-treatment (whole blood, hair, crude oil, vegetation, food), a two-chamber pyrolytic atomiser was developed. Its design allows to separate the processes of evaporation and dissociation of mercury compounds as well as to simplify the matrix components in the gaseous phase in real time. Results of analyses of samples with simple and complex matrices are shown in the paper. (C) 2004 Elsevier B.V. All rights reserved.
