摘要：

The dependence of sucrose sorption isotherm data obtained by inverse gas chromatography on column material was studied. Columns made of polyamide glass, copper and stainless steel were used. The results obtained indicate that the interaction between water vapour and the column wall cannot be ignored when products with very low equilibrium moisture content are considered.
