一般描述

Carboxen是由高分子前体高度改性而成的人造碳吸附剂。这种粒子既不会像树脂一样发生塑性变形,也不会像活性炭一样产生细微颗粒。以干燥形式储运。Carboxen作为衍生树脂适合各种去除小分子和大分子杂质的纯化应用。气相和液相纯化皆可。包括,去除原料药(API)中的均相催化剂,在生化纯化中去除高风险杂质(如,单抗中的残留宿主细胞蛋白),去除重金属,纯化氯化物,去除可萃取物和可浸出物。大小不一的渐变孔径改善了吸附和解吸的热力学和动力学特性。Carboxen形式多样,具有不同的孔结构(微孔、中孔和大孔比例不同)、比表面积和表面pH。

The headspace solid-phase microextraction (HS-SPME) efficiencies from vegetable oil of the recently available Carboxen-poly(dimethylsiloxane) (PDMS) and divinylbenzene-Carboxen-PDMS fibres were found to be much greater than those of the PDMS fibre for a number of volatile contaminants. Using these Carboxen-based fibres
