采用配备RRHT 色谱柱和方法的1200 快速高分离度液相色谱(RRLC) 快速分析聚丙烯均聚物中酚类抗氧剂和芥酸酰胺润滑添加剂
Abstract:
采用液相色谱-紫外/可见检测器，在ASTM D6042方法的指导下，分离和检测了聚丙烯均聚物中维生素E (tocopherol)，酚类抗氧剂和芥酸酰胺润滑添加剂。采用安捷伦快速分离液相色谱和ZORBAX (RRHT) Rapid resolution high throughput 柱，可在相同或提高分离度的情况下，快速分离抗氧剂。使用安捷伦方法转换器，基于仪器参数，柱尺寸和粒径大小等参数，采用简单转换、速率转换、分离度转换等三种模式将ASTM 方法转换为新方法。
Vitamin E (tocopherol), phenolic antioxidants and erucamide slip additives in polypropylene homopolymer formulations were resolved and detected using liquid chromatography with ultraviolet/visible detection, under guidelines suggested by ASTM Method D6042. Using the Agilent 1200 Rapid Resolution LC system with Agilent ZORBAX RRHT columns, the antioxidants could be rapidly separated with the same or improved resolution. The Agilent method translator was used to transfer the ASTM method into new methods based on the instrument parameters, column dimensions, and particle size in three modes: simple conversion and speed optimized and resolution optimized methods.
