Sigma-Aldrich - Mycotoxin Analysis Analytical Standards
Mycotoxins are products by fungal genera like Aspergillus, Fusarium, Penicillium, etc. These toxic secondary metabolites are harmful to animal and human health if they enter the food chain via contaminated crops and fruits or through processed food and feed products. Therefore, in at least 100 countries limits are set for mycotoxin levels for food and feed. For a precise detection of all regulated mycotoxins, Sigma-Aldrich offers a comprehensive range of ...

SupelMIP Molecularly Imprinted Polymer SPE Cartridges
SupelMIP SPE is based on molecularly imprinted polymer (MIP) technology. The SupelMIP SPE products consist of highly cross-linked polymers that are engineered to extract a single analyte of interest or a class of structurally related analytes of interest 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. Each SupelMIP phase offers tailor-made selectivity for the extraction of trace analytes in complex matrixes. Its superior cleanup and selectivity provide faster/simpler sample prep methods, better MS compatibility (reduced ion suppression) allowing analysts to achieve lower detection limits and improved sensitivity.
