Theory on frequencymetric titration has been proposed based on equivalent circuit of piezoelectric quartz crystal (PQC) in liquid and oscillation equation of TTL-PQC oscillator, and the theoretical equation derived representing the frequency shift with respect to the solution conductivity. Practical examples of various types of titration are given in this paper. 相似文献
