Sigma-Aldrich Aflatoxin Mix 4 solution

Multi-component aflatoxin standard for HPLC, UHPLC, and GC analysis

Sigma-Aldrich™ Aflatoxin Mix 4 is a high-precision, ready-to-use analytical standard designed for accurate quantification and calibration of the four naturally occurring aflatoxins: B1, B2, G1, and G2. Prepared in acetonitrile with certified concentrations, this multi-component mix provides traceability, reproducibility, and accuracy for food safety testing, mycotoxin surveillance, laboratory accreditation workflows, and regulatory compliance.

Aflatoxins are toxic secondary metabolites primarily produced by Aspergillus flavus, A. parasiticus, and A. nomius. Among the 20+ aflatoxins known, B1, B2, G1, and G2 are of greatest significance in regulatory testing due to their toxicity and prevalence in contaminated food and agricultural commodities.
