SupelMIP® SPE - Bisphenol A
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 chemi…

High purity
Assay
I have analyzed bisphenol in drinking water bottles.
Review Date: 23 May 2022 | Sigma-Aldrich Supelco
Still need more trials.
Water sample from drinking bottles
Not too successful, did not concentrate enough to be detected via GC-MS. Need to adjust the priming and elution.

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.
Features and Benefits:
- Highly selective SPE for trace analysis in complex matrices
- Achieve lower detection limits
- Significant time and cost savings
- Improved MS-compatibility
Extraction and Quantitation of Bisphenol A (BPA) from Broth-Based Soup Matrices Using Molecularly Imprinted Polymer Solid Phase Extraction
This application illustrates the use of the SupelMIP® SPE-Bisphenol A for the extraction of BPA from beef and chicken broth matrices prior to chromatographic analysis. In addition to excellent analyte recovery and reproducibility, the MIP SPE extraction and cleanup method provided sufficient matrix interference removal, facilitating quantitation. In addition, this method allows for detection and quantification of BPA levels that were as low as 60 ng/g, which is lower than current specified EU regulations.
