一般說明
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。

The method for determination of low concentrations of chloramphenicol in bovine and porcine urine was developed. Sample cleanup was performed by Molecular Imprinted Polymer (MIP) columns. Confirmatory analyses were conducted using GC/MS-NCI after derivatisation (silylation). The described method was fully validated according to CD 2002/657/EC, CCa was 0.06 ng/mL, CCb was 0.1 ng/mL. This method is considerably robust and allows to process even very dirty samples. The described procedure is very simple, low-time-consuming, provides high throughput of examinated samples, and could be used for routine screening and confirmatory analyses as well.
