Metrosep A Supp 1 HS is a special separator, which has been developed for rapid analysis of orthophosphate in cola soft drinks. Its short length of 50 mm and very low ion-exchange capacity also allow rapid analysis of some common inorganic anions in weakly contaminated sample matrices. The corresponding hyperbranched polymer, the lonPac Fast Anion IIIA (see Section 3.4.3), which has been developed for the same application, is more robust due to its chemistry and standard length of 250 mm. Moreover, it elutes citrate faster and can, therefore, be applied for analyzing diet cola drinks, too.
