An electrode less piezoelectric quartz crystal was constructed with a quartz plate placed on a horizontal metal plate electrode, where a single drop of electrolyte solution holding a platinum wire electrode was loaded. The quartz plate was oscillated with the connection of the electrodes to an oscillator. The frequency was shifted with the adsorption of the precipitate resulting from the reaction of calcium ion in the electrolyte solution with dodecyl sulfate ion (SDS) in a sample solution dropped on the electrolyte solution. The frequency shifts resulting from the adsorption of the precipitate depended on the size of the drop, the size of the metal plate electrode, the composition of the electrolyte and the sample solutions. SDS over the range 5100μM could be determined with a relative standard deviation of 5.3% (n = 5) for 50 μM. The adsorbing ion-pair of dodecyl sulfate ion with cetyltrimethylammonium ion resulted in the determination of SDS over the range 0.210 μM with a good reproducibility of 6.8% of the relative standard deviation (n = 4) for 5 μM.
