Aflatoxins and Ochratoxin A: Sensitive Quantitation with the Right Standards
Aflatoxins and ochratoxin A are among the most regulated mycotoxins. This article explains how to achieve sensitive quantitation using appropriate reference standards in HPLC and LC-MS workflows.
Aflatoxins and ochratoxin A are among the best known regulated mycotoxins because of their toxicity and their frequent association with nuts, spices, cereals, coffee, dried fruit, and related commodities. Their analysis often demands high sensitivity, which increases the importance of carefully prepared reference standards. Fluorescence detection remains useful in many workflows, while LC-MS offers added flexibility for broader confirmation. In either case, calibration accuracy depends on standard purity, solvent compatibility, storage conditions, and protection from degradation. These details matter because laboratories often work close to regulatory thresholds. A practical article should explain why laboratories sometimes need both mixed and single-component standards. Mixed standards improve routine efficiency, while individual standards help with peak confirmation, troubleshooting, and instrument qualification. This balance is especially important in multi-product food labs where testing menus shift seasonally. The commercial opportunity is clear: customers in this segment often reorder standards regularly, along with sample prep consumables and chromatography accessories. Content that helps them think in terms of workflow reliability rather than single purchases is more likely to support repeat business.
