Cromatografia, Fase estacionária

Os sorventes auxiliam na separação de compostos de misturas em qualquer método de cromatografia. Sorventes cromatográficos prontos para uso tornam qualquer procedimento de isolamento, identificação ou purificação rápido e simples. Sorventes de fase estacionária são oferecidos em diferentes tamanhos de partículas ou polaridades para corresponder às propriedades químicas e físicas dos compostos da amostra, garantindo resultados precisos. Os sorventes cromatográficos podem vir com ou sem aditivos, como aglutinantes para estabilização ou indicadores fluorescentes para compensar faixas de ultravioleta de difícil visualização.

Ion exchangers

Supplier: Merck

In general, ion exchangers consist of a cross-linked polymer matrix with a uniform distribution of fixed ionic groups sited throughout the resin structure. These must be balanced by a similar number of ions of the opposite charge, (counter ions) to maintain electrical neutrality. Cation exchangers therefore, exchange and enrich only cations, anion exchangers only anions. In contrast adsorber resins have a non ionic, but depending on the structure, a somewhat polar character, and don't adsorb stoichiometrically both: anions, cations, as well as uncharged compounds.
