Frequently Asked Questions

Can I use these columns for both Aflatoxins and Ochratoxin simultaneously?

Yes, the IAC Combi Afla+Ochra columns are specifically designed for simultaneous extraction of both Aflatoxins (B1, B2, G1, G2) and Ochratoxin A in a single pass.

What is the maximum sample volume the column can process?

The column capacity is 1.8 μg for Aflatoxins and 3 μg for Ochratoxin per cartridge.

Which analytical method is recommended?

HPLC-FLD (High-Performance Liquid Chromatography with Fluorescence Detection) is recommended for optimal results.
