Art. No.: RBRP89 / RBRP89B

Intended use

Multi-mycotoxin immunoaffinity columns for simultaneous detection of aflatoxins B1, B2, G1, G2 and ochratoxin A in a wide range of commodities in conjunction with HPLC or LC-MS/MS.

General Information

The procedure is based on monoclonal antibody technology, which makes the test highly specific, sensitive, rapid and simple to perform. Improved clean-up and concentration of toxins from complex food matrices results in reduced chromatography interference and lower detection limits. The columns contain a gel suspension of monoclonal antibodies specific to the toxins of interest. Following extraction of the toxins the sample extract is filtered, diluted and passed slowly through the immunoaffinity column. Any toxins which are present in the sample are retained by the antibody within the gel suspension. The column is washed to remove unbound material and the toxins are then released from the column following elution with solvent. The eluate is collected and injected prior to analysis by HPLC or LC-MS/MS. Aflatoxins are required to be derivatised when analysed by HPLC.


  • The columns have been validated and approved by Nestlé.
  • One sample preparation and extraction for the analysis of aflatoxins and ochratoxin, saving time.
  • Simultaneous detection of aflatoxins and ochratoxin in a single HPLC run. Alternatively, analysis can be performed in a single LC-MS/MS run.
