摘要：

The Cu(II)-neocuproine method is applied to the determination of reducing sugars in several products using a flow injection system. Two different sugars have been combined as standards. A dialysis procedure has been assayed to avoid tedious decolorisations with charcoal, three different types of membranes being tested for this purpose. With the most suitable one, a linear calibration graph was run over the range between 1.2 and 7.2 g litre-1 of glucose, sampling frequency being 40 h-1. Finally, the results obtained have been compared with those provided by a batch standard method.
