Comparison of Afla Test-P and Afla-M_1 Column for Aflatoxin M_1 Analysis in Milk

摘要

The amount of aflatoxin M_1(AFM_1) in milk using Afla Test-P column and Afla-M_1 column was compared. Fluorometer and high performance liquid chromatography(HPLC) were used as detectors for both kinds of column. It was found that HPLC was appropriate for both types, resulting in a 78/100 recovery of 1 ppb spiked mike from Afla Test-P column and 86/100 for Afla-M_1 column. However, using Afla Test-M as a calibration standard, fluorometer was proven not to be appropriate for neither types of column.
