Total Aflatoxin Immunoaffinity Column

This series of immunoaffinity columns exhibits high selectivity for enriching and purifying mycotoxins present in food, feed, grains, and similar materials. Featuring straightforward operation and high recovery rates, they are suitable for sample preparation and precise analytical testing.

• High Specificity: Efficiently identifies target substances

• High Stability: RSD < 5%

• High Recovery Rate: Spiked recovery rates reach 90%–105%

• High column efficiency: Stable flow rate minimizes column blockage

• Strong enrichment capability: Efficiently adsorbs target substances for enhanced detection

• Powerful purification capability: Eliminates interfering substances to improve detection accuracy

• Broad applicability: Compliant with mainstream official analytical methods, suitable for toxin detection standards in GB5009 series and various pharmacopoeias

1. Use the affinity column within its expiration date.

2. Allow the column to reach room temperature (22–25°C) before use.

3. Store the column at 2–8°C; do not freeze.

4. Sample volume: Adjust sample volume as needed, ensuring the extraction solution volume is correspondingly modified.

5. Column capacity: 200 ng. If the toxin concentration in the sample divided by the dilution factor exceeds the column capacity, reduce the sample volume and retest.

6. pH: The pH of the sample solution must be between 6–8. Adjust pH with hydrochloric acid or sodium hydroxide if outside this range.

7. Using the same solvent as the mobile phase during instrument analysis eliminates solvent effects.

8. Aflatoxin B1 is carcinogenic; wear gloves, masks, and other protective equipment during handling.

9. Soak used containers and aflatoxin B1 solutions overnight in sodium hypochlorite solution (5% v/v).
