SupelMIP SPE 核黄素（维生素B2） 25mg/10ml,50支/盒 高选择性的 MIP 相，用于从牛奶和其他含水样品中选择性萃取核黄素（维生素 B2）。 SupelMIP 固相萃取 &mdash 核黄素是开发用于当存在结构相似的维生素和类似物时萃取核黄素。稳定获得高达 85% 的回收率。 SupelMIP 固相萃取相由 MIP Technologies AB 所开发，它是分子印迹聚合物的的领导者和商业先锋之一。此固定相可用于大规模分离、分析色谱和样品制备。 SupelMIP 固相萃取产品线是由高度交联聚合物组成。该类特殊的固定相对提取单个目标分析物或结构相似的分析物具有极高的选择性。 在 MIP 合成过程中模仿目标分析物设计模板分子，该模板分子形成的洞穴或印记正好与目标分析物的立体和化学结构相匹配，这使得在 MIP 合成中引入选择性成为可能。 精心设计的印迹点是通过分子模拟、实验设计或筛选方法形成的，该印记点或洞穴能够提供多种与目标分析物的相互作用点。这可实现固相和分析物之间更强的相互作用。从而，在固相萃取方法中可允许更苛刻的冲洗条件，最终得到更干净的萃取物。由于萃取选择性得到显著提高，观察到的背景更低，使得分析物的检测限更低。
