Simultaneous determination of potassium and nitrate ions in mouthwashes using sequential injection analysis with potentiometric detection.


Two methods for the determination of potassium nitrate in mouthwashes, used against dentin hypersensitivity, have been simultaneously implemented in an sequence injection analysis (SIA) system. In addition to in-line dilution of the samples, the equipment simultaneously detected potassium and nitrate using two tubular potentiometric detectors, selective to… (More)
