Descripción general
The SupelMIP SPE line consist s of highly cross-linked polymers that are engineered to extract a single analyte of interest or a class of structurally related analytes with an extremely high degree of selectivity. This is possible because selectivity is introduced during MIP synthesis in which a template molecule, designed to mimic the analyte, guides the formation of specific cavities or imprints that are sterically and chemically complementary to the analyte(s) of interest.
By careful design of the imprinting site, either by molecular modeling, experimental design, or screening methods, the binding cavities can be engineered to offer multiple interaction points with the analyte(s) of interest. This leads to a stronger interaction between the solid-phase and the analyte(s). As a consequence, harsher wash conditions can be tolerated during SPE methodology resulting in cleaner extracts. Because extraction selectivity is significantly improved, lower background is observed allowing analysts to achieve lower limits of detection.

Aplicación
Chloramphenicol is a broad-spectrum antibiotic that is currently banned by a number of countries including the EU, the US, and Canada. This MIP phase and associated method offer a simple, efficient, and highly selective extraction method for quantiting chloramphenicol in food products and biological matrices. Detection limits well below the minim required performance limit (MPRL) are achieved consistently.

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.
