| Abstract: | Anew PVCmatrix membrane double-barrelled calcium ion-selective microelec-trodc based on liquid ion exchanger has been designed and constructed. The tip diameter of about 2.5μm as well as lower selectivity coefficients for K+, Na+ and Mg2+ are adequate for intracellular measurements of Ca2+ activities.The inner wall of the selective channel was made by hydrophobic treatment with alcohols. By means of this microelectrode some physiological phenomena related to Ca2+ activities have been studied, and Ca2+ concentrations in clinical microsamples have also been determined. |
