高效液相色谱分析富勒烯中C_(60)和C_(70)的新方法

A NEW METHOD FOR ANALYSIS OF C_(60) AND C_(70) IN FULLERENES BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY

提出了一种用于分离与分析富勒烯中Ｃ＿（６０）和Ｃ＿（７０）的高效液相色谱新方法，该方法用辛烷基键合相作色谱柱固定相，以乙醇－氯仿（体积比为７５：２５）溶剂作流动相，用紫外检测器检测，其分离度大于２．５，分析时间小于９ｍｉｎ，最小检测量为１×１Ｏ￣（－１１）ｇ。

A new method for analysis of C_(60) and C_(70) in fullerenes by HPLC on octanc group bondedphase column with ethanol-chloroform（75 ： 25） as the mobil phases and UV detector hasbeen studied． The resolution between C_(60) and C_(70) was more than 2． 5； the separation time wasless than 9 min and the minimum detectbility was 1 ×10^(-11)g。
