有机载体(即高分子多孔小球)系聚芳烃型交链树脂,这种树脂具有均匀的孔径,不溶于水,也不溶于许多有机溶剂。目的上试一厂供应的有机载体有四种筛目,即40/60、60/80、80/100、100/120,每一种的包装单位为25g。高分子多孔小球适用于分离各种气体、沸点不超过250℃或分子量不大于300的化合物,特别推荐用于分析有氢链组成的有机化合物水溶液,例如:氨、醇、二元醇、游离酸,这种高分子多孔小球填充在长柱中,其分离能力类似于分子筛柱。这种高分子多孔小球系由二乙烯苯与乙基苯乙烯共聚而成,此外,也可引进一些单官能团、双官能团单体例如,丙烯腈
Organic carriers (ie, polymeric porous beads) are polyaromatic cross-linked resins that have a uniform pore size and are insoluble in water and insoluble in many organic solvents. The purpose of the first plant to test the supply of organic carriers have four kinds of mesh, that is, 40/60, 60/80, 80/100, 100/120, each packaging unit is 25g. Polymer porous beads suitable for the separation of a variety of gases, the boiling point of not more than 250 ℃ or molecular weight of not more than 300 compounds, especially recommended for the analysis of hydrogen chain composition of organic compounds such as aqueous solution, such as: ammonia, alcohol, glycol, free Acid, which is packed in long columns of porous macromolecules with separations similar to molecular sieve columns. This polymer porous beads from divinyl benzene and ethyl styrene copolymerization, in addition, you can also introduce some monofunctional, bifunctional monomers such as acrylonitrile
