Description

Application

Developed for the class-selective extraction of polyaromatic hydrocarbons (PAHs) from edible oil (e.g., olive oil, peanut oil, corn oil) and related sample matrices.

The PAHs that have been tested include: chrysene, benzo[a]anthracene, benzo[k]fluoranthene, benzo[b]fluoranthene, benzo(a)pyrene, indenol[1,2,3-cd]pyrene, dibenzo[a,h]anthracene and benzo[ghi]perylene.

The SupelMIP SPE - PAHs is not suitable for extrracting smaller PAH compounds (2-3 rings); and for quantitative extraction of pyrene.


Features and Benefits

• Highly selective SPE for trace analysis in complex matrices
• Achieve lower detection limits
• Significant time and cost savings
• Improved MS-compatibility

General description

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.
