摘要/Abstract

摘要：提出以纯水为流动相，在不外加任何辅助剂的条件下，用尺寸排阻色谱法(SEC)分离巯基丁二酸(MSA)单层包裹的粒径约1～5 nm的水溶性小金纳米簇.建立了其稳定的色谱条件.环境友好，操作简单，重现性好.

关键词： 金纳米簇, 尺寸排阻色谱, 分离, 色谱条件

Abstract: Using pure water as a mobile phase without any additional adjuvant,it was established that stable chromatography conditions separated water-soluble small gold nanoclusters capped by 2-mercaptosuccinic acid (MSA) monolayer in the size range of 1～5 nm by size exclusion chromatography (SEC).It was environment-friendly and easy to operate.The reproducibility was good.

Key words: gold nanoclusters, size exclusion chromatography, separation, chromatography conditions
