Multi-analyte affinity column for analyzing aflatoxin, fumonisin, ochratoxin and zearalenone

摘要

A multi-analyte column is disclosed. The column may contain at least one unit of resin having ochratoxin specific affinity and, for each unit of resin having ochratoxin specific affinity, the column further contains about 0.95 to 1.05 units of resin containing antibody having specificity for zearalenone, about 1.9 to 2.1 units of resin containing antibody having specificity for aflatoxin and about 2.8 to 3.2 units of resin containing antibody having specificity for fumonisin. One unit of resin is the quantity of resin containing antibody that will bind 50 ng of aflatoxin, 3300 ng of fumonisin, 50 ng of ochratoxin or 1140 ng of zearalenone, respectively.
