Abstract
A system for the separation and detection of inorganic anions in a sample, the system comprising: • a separation channel with an inner coating of three or more alternating layers of a cationic polymer (e.g. hexadimethine bromide) and an anionic polymer (e.g. polystyrene sulfonate), wherein the first layer and the final layer are cationic polymer layers; • a detector for detecting inorganic anions that pass through a detection zone of the separation channel; • an injection system for injecting fluids including sample solutions and background electrolyte into an inlet end of the separation channel; wherein the background electrolyte comprises polyethyleneimine. Also described are corresponding methods, separation capillaries and cartridges for use in the system.
