Ion-Selective Electrode Reviews, Volume 2 is a six-chapter book that begins with a description of the uses of the piezoelectric crystal detector in analytical chemistry. The uses of known addition, Gran's plots, and the related methods with ion-selective electrodes are then explained. Subsequent chapters discuss the role of ion-selective electrodes in cystic fibrosis studies and surface effects in relation to the response of solid-state ion-selective electrodes. The analytical control of drug-type substances with membrane electrodes is also addressed.
