General description

助留机理：反相
样品基质相容性：水溶液或甲醇溶液

  • 聚酰胺树脂：粒度：50-160μm，表面 pH：4.5-7.5，密度：0.2-0.3cm3/g，含水量：< 5%
  • 用于按照反相机理，通过化合物羟基基团与树脂的酰胺基团之间的强烈的氢键作用，从水溶液或甲醇溶液中吸附极性化合物（-OH 基团，尤其是酚醛化合物）
  • 用于萃取单宁、叶绿素、腐殖酸、药理活性的类萜、黄酮类、没食子酸、儿茶酚 A、原儿茶酸和间苯三酚
  • 也用于萃取芳族羧酸和硝基芳香化合物
  • 不可逆地保留苯醌

Application

Discovery® DPA-6S SPE Bulk Packing may be used as a sorbent for dispersive soilid phase extraction followed by liquid chromatography and gas chromatographic determination of acrylamide in various food matrices.

Isolation techniques for anthocyanidin 3,5-diglucosides and their derivatives from three types of supramolecular pigments were newly developed using two SPE (Discovery DPA-6S and DSC-SCX) cartridges. Initially, malonylawobanin from commelinin supramolecular complex yielded 79.5% with 85.7% purity using DPA-6S, while DSC-SCX
