自Hollis首次介绍大孔聚芳烃小球用作气相色谱固定相以来,已有多种牌号商品;而类似骨架的大孔苯乙烯-二乙烯苯共聚物(俗称白球)早已大规模地用于离子交换树脂的生产中,但是对于必然伴生的小颗粒白球(例如小于70目)一般弃去不用.我们以某工厂筛分掉的白球为原料,研究了它们用作气相色谱固定相的可能性. Since Hollis first introduced the use of macroporous polyene beads as a GC stationary phase, a wide range of grades have been commercially available; and macroporous styrene-divinylbenzene copolymers (commonly known as white balls) of similar skeleton have long been used in large scale for ion Exchange resins, but are generally discarded for small particles that must be associated (eg, less than 70 mesh) .We used the white balls screened off at a factory as raw materials to investigate their potential as GC stationary phases.
