Short summary
The processes of the interaction of sulfur dioxide with water ice are still not fully understood. We demonstrate how the well established technique of gas chromatography can be used to investigate interactions of sulfur dioxide with a crystalline ice film deposited in a fused silica wide bore column. Our experiments reveal that the interaction is a combination of three processes: (i) physisorption, (ii) dissociative reaction with water and (iii) slow uptake into bulk ice.
