摘要
本文将示差折射率检测器与质量检测器串联用高效液相色谱法测定了甜玉米和可口可乐中的糖份。以质量检测器测定浓度小的糖份,以示差折射率检测器测定浓度大的糖份。可以一次进样,同时测定样品中浓度大小相差很大的多种糖份。
The determination of sugars in sweet corn and Coca Cola by HPLC with differential reflective index detector and mass detector connected in series is reported. Sugars in low concentrations are detected by mass detector, while those in high concentrations are detected by differential reflective index detector. Samples with great difference in sugar concentrations thus can be analyzed simultaneously by HTLC after one injetion.
