Allgemeine Beschreibung

The fluorescence of 2-naphthalenesulfonic acid (NSA) is effectively quenched by colloidal silver via photoinduced interfacial electron transfer from the excited singlet of NSA to silver. Adsorption behavior of NSA on a conventional macroporous resin Amberlite XAD4 and hypercrosslinked resins NDA101 and NDA100 has been investigated.

Capillary electrophoresis is commonly applied for the analysis of pharmaceutical products due to its high separation efficiency and selectivity. For this purpose, electrospray-ionization-(ESI)-interfering additives or electrolytes are often required, which complicates the identification of impurities and degradation products by mass
