Abstract

Sugar analysis in the beet industry presents some difficulties due to the highly complex composition of the raw products. This is particularly important in molasses, which contains a considerable ionic component. However, precise determination of raffinose concentration is necessary to optimize the crystallization process. Purification of raw products on mixed‐bed ion exchangers followed by passage through a ODS precolumn is performed before the actual chromatographic step. These steps must be automated in order to improve precision and productivity. A completely automatic system, designed for maximum stability of chromatographic columns and good analytical precision of results is presented.
