Calibration Behavior in Charge Detection

The charge detector contains both anion- and cation-exchange membranes in a configuration to deionize the influent coming from the suppressor. Strongly dissociated ionic species such as hydrochloric acid are removed completely by the

In contrast to RPLC, UV detection is of minor importance in ion chromatography, but is considered a welcome supplement to conductometric detection. It is a disadvantage of direct UV detection that most inorganic anions do not possess an appropriate chromophore. Thus, they generally absorb at wavelengths below 220 nm [38]. This was corroborated by the works of Reeve [39] and Leuenberger et al. [40], who separated inorganic anions on a chemically bonded cyano- or 

One of the most important applications of UV/Vis detection is photometric determination after derivatization of the column effluent First of all, this includes the determination of transition metals after reaction with 4-(2-pyridylazo)-resorcinol (PAR).
