Surface and Volume Resistivity of Pyrex Glass Used for Liquid Membrane Ion-Sensitive Microelectrode, the electrical resistivity of the surface of the glass crmust be high, and so must the resistance through the wall of the pipette. The behavior of a fine-tipped microelectrode depends on many factors, and direct examination of electrode responses has led to conflicting ideas about leaks (e.g., [11

Computer-Assisted Processing of Ion-Selective Electrode Measurements, of the two. The last of these also clearly exhibits noise due to the phase shift between the electrode signals. This noise can of course be eliminated by additional filtering. However, essential information for a critical examination of the ion activity changes would then be lost. In order to analy

Continuous Potentiometric Measurement of Different Ion Concentrations in Whole Blood of the Extracouid membrane electrodes. The usefulness of the membranes was evaluated by comparison with independent methods. Because of the requirement for membrane electrode systems with long lifetimes, the original membranes have been modified by using a novel, highly lipophilic PVC plasticizer. It has turned o

Monitoring Ca2+, pH, and PCO2 in Circulating Arterial Blood by Means of Ion-Selective Electrodes inrmits multiple sensors to be used. Such circuits are often arterio-venous shunts . These offer a steep pressure drop, and thus brisk extracorporeal flow, but reduce peripheral resistance and systemic arterial pressure, unless extra hydrodynamic resistance is incorporated in the circuit as a

Plastic H+-Sensitive Membranes for In Vivo pH Measurements,ations using H.-sensitive electrodes in humans. In 1976, Le Blanc et al. developed a plastic H.-sensitive membrane consisting of block copolymer elastomers containing 60% polysiloxane and 40% poly (bisphenol-A-carbonate) mixed with .-octadecyloxy-.-chlorphenylhydrazone-mesoxalonitrile (OCPH).

The Applicability of Fluorescence Indicators to Measure Hydrogen Ion Activities by Optimizing Accurndicators generally, we have developed special fluorescence sensors, optodes, in which the indicator molecules are separated from the medium by a protecting membrane which is permeable for the substance to be measured . Thus, interactions of proteins or colloids of biological fluids with th
