Abstract

A systematic investigation was carried out of the conditions employed for the post-column iodination reaction used to enhance fluorescence sensitivity of aflatoxins B1 and G1 in reverse-phase HPLC. The effect of post-column reaction coil tubing dimensions, coil temperature, eluent and reagent flow rates and reagent concentration were examined and the optimum choice of each established. The maximum achievable sensitivity was shown to be 20 pg of B1 injected on column.

摘要

对用于反相高效液相色谱法中增强黄曲霉毒素B1和G1荧光灵敏度的柱后碘化反应所采用的条件进行了系统研究。考察了柱后反应盘管尺寸、盘管温度、洗脱液和试剂流速以及试剂浓度的影响，并确定了各自的最佳选择。结果表明，柱上进样20 pg B1时可实现最大灵敏度。
