采用快速高分离度液相色谱仪快速分析聚合物中酚类抗氧剂和氨基化合物添加剂
Abstract:
液相色谱-紫外/可见检测器是一种分析高聚物中添加剂的强有力工具。本应用给出了采用Agilent 1200 快速分离液相色谱系统分离抗氧剂和氨类润滑剂。同传统的液相色谱比，本系统在不损失分离度、精密度和灵敏度的情况下，客人快速分离抗氧剂。同时讨论了色谱柱的化学性能和温度对分离和样品制备方法的影响。
Liquid chromatography with ultraviolet/visible (UV/VIS) detection is a powerful approach for analyzing additives in polymer formulations. This application illustrates the
use of the Agilent 1200 Series Rapid Resolution LC (RRLC) system for the separation of antioxidants and erucamide. The system can operate significantly faster than conventional HPLC without sacrificing resolution, precision, or sensitivity. The column chemistry and temperature influence on the separation and the sample preparation method are also discussed.
