Two-dimensional chromatography is on the way up in the food and drinks industry. It involves two chromatography columns placed after each other, resulting in a quadratic increase of the resolution. This creates new possibilities for developing (functional) foods and for checking the quality of raw materials and end products.
**********
The principle of every chromatographic separation is retention. Some molecules are 'braked' more intensively by the column packing than others. In two-dimensional chromatography two columns are placed after each other, which separate on the basis of different mechanisms.
The first column separates, for instance, ...
