Frequently Asked Questions

What is the difference between this multiplex column and single-target IAC products?

The Combi Afla+Ochra+Zeara column enables simultaneous extraction of three major mycotoxin groups in a single sample preparation step, reducing analysis time and sample volume requirements compared to sequential single-target columns.

Can these columns be used with automated sample preparation systems?

Compatibility with specific automated platforms depends on column connector specifications and flow rate requirements. Contact technical support for system integration details.

Are cross-reactivity percentages constant across all sample types?

Cross-reactivity data reflects immunological binding characteristics and remain consistent. However, actual recovery of structural analogs (e.g., zearalenone metabolites) may vary by matrix composition and extraction pH.
