RCX-30 The Hamilton RCX-30 material is a strongly basic anion exchanger. It was specially developed for the separation of complex carbohydrate mixtures, both in isocratic and in gradient. Compared to the Hamilton RCX-10 column, the RCX-30 column has a higher ion exchange capacity. Therefore, chemically very similar carbohydrates can be separated on this column. The stationary phase is stable over a wide pH range (from 0 to 14). The mobile phase required for the sugar separations is again caustic soda, but in higher concentrations compared to the RCX-10 column. Thus, the separation conditions are also optimal here for the use of a pulsed amperometric detector, for the very sensitive and selective detection of sugars. Of course, in higher concentrations carbohydrates can also be determined using an RI detector. The filling material is available in columns with internal diameters 4.1 mm and 4.6 mm, both in stainless steel and in PEEK. Guard columns are also available in stainless steel and PEEK.
