Abstract
A flow-through optosensor for quinine is described. It has been develo ped in conjunction with a flow-injection analysis system and uses immo bilized beta-cyclodextrin as the sensing agent. The detection limit fo r quinine was 0.20 ng ml(-1) with a relative standard deviation of 2.1 % for the determination of 0.05 mu g ml(-1) (n = 7) of quinine. The me thod has been successfully tested for the determination of quinine in some pharmaceutical preparations.
