Frequently Asked Questions

What is the minimum sample volume required for analysis?

The 3 mL column volume accommodates standard sample extracts. Refer to the application protocol for specific sample preparation requirements.

Are the columns compatible with automated sample preparation systems?

Yes, the standard 3 mL column format is compatible with most automated extraction platforms used in food analysis laboratories.

What is the shelf life of these immunoaffinity columns?

Shelf life specifications are available upon request from Novatek Analitik Sistemler A.Ş. Storage conditions must follow manufacturer guidelines.

Can these columns detect other mycotoxins besides aflatoxins and ochratoxins?

These columns are specifically designed and validated for aflatoxins (B1, B2, G1, G2) and ochratoxin A/B detection. For other mycotoxins, dedicated columns are recommended.

What analytical instruments are compatible with these columns?

The columns are validated for use with HPLC and LC-MS/MS systems for both qualitative and quantitative analysis.
