摘　　要：分子蒸馏是一种新型的高效液-液分离技术。本文对分子蒸馏的原理和设备组成以及国内外典型分子蒸馏设备的结构、特点和应用进行了简要归纳。对该技术在样品分析前处理工作中的应用探索进行了介绍,通过对分子蒸馏装置进行全新的设计,运用载体、携带物和综合蒸馏技术完成了待测样品中微量成分的分离和富集,建立了一种新的样品前处理模式。Molecular distillation is a liquid-liquid separation technology which is a new and high efficiency method. The principle and equipment composition of molecular distillation are briefly introduced. The structure, characteristics and application of the domestic and overseas molecular distillation equipment are summed up. The article introduces a new design of molecular distillation which is applied to sample preparation. It uses carrier, transporter and multiple distillations to finish the separation and enrichment of trace comoonents.
