一般說明

Retention Mechanism: Ion-Exchange
Sample Matrix Compatibility: Aqueous solutions (biological fluids, water)

  • Sulfonic acid functionalized hydrophilic modified styrene polymer
  • Developed for the extraction of a highly broad range of compounds from aqueous samples
  • Retention predominately based on ion-exchange; however, because the phase is hydrophilic modified, it is amenable to polar compounds as well.

特點和優勢

  • 价格低廉但具有出色的样品制备性能
  • 可用于通用方法 — 在方法开发时省时、成本低并减少麻烦
  • 容量更大,床重更轻 = 洗脱体积更小 = 处理样品更迅速
  • 能忍受过度干涸,可用于更极端条件的方法
  • 低紫外和质谱可提取物,背景更低,灵敏度更高
  • 严格的生产和质量控制原则提供更好的批次之间、管之间以及孔之间的一致性,能获得更好的准确度和精度
