摘要: Based on the linear relation between frequency response of piezoelectric quartz crystal sensor and conductivity solution to be measured, calibration models for quantitative analysis acid base systems are derived verified both theoretically experimentally. Then determinations aspirin penicilline were done with technique. The results two true pharmaceutical indicate that models, combining regression, can give precise accurate concentration estimates, which reduce influence presence interferences.
