LOPE

Continuous Potentiometric Measurement of Different Ion Concentrations in Whole Blood of the Extraco addition to the improved lifetime, an increased EMF stability of the electrodes was observed. The applicability of the four membranes when incorporated in a flow-through electrode system for blood measurements is documented in the light of continuous monitoring in the extracorporeal circulation of animals.

A New Potential Electrode for Glucose Measurements,d an enzyme electrode by Updike and Hicks [3], either the decrease in dissolved oxygen consumed by the enzyme reaction or the formation of hydrogen peroxide generated as a product of the degradation of glucose is measured by amperometric polarography.

情節(jié)劇

Computer-Assisted Processing of Ion-Selective Electrode Measurements,d by additional filtering. However, essential information for a critical examination of the ion activity changes would then be lost. In order to analyze this noise and to calculate the actual ion activities, and in view of the volume of data involved, the application of a computer is indicated.

Plastic H+-Sensitive Membranes for In Vivo pH Measurements,lastomers containing 60% polysiloxane and 40% poly (bisphenol-A-carbonate) mixed with .-octadecyloxy-.-chlorphenylhydrazone-mesoxalonitrile (OCPH). They found that electrodes made of this material had excellent Nernstian characteristics (Fig. 1).

Intracellular pH Measurements In Vivo with a Newly Designed Double-Barrelled Microelectrode and itsnd, even though separate compartments at different pH give separate peaks in .P NMR spectra, it seems to be difficult to follow changes in the extracellular space in vivo. By the use of pH-sensitive electrodes, on the other hand, it becomes possible to measure in the extracellular as well as in the intracellular compartment.

Bravado

Ion Transport in Asymmetric Artificial Membranes Mediated by Neutral Carriers, directed flow of hydrogen ions, as induced by a pH gradient. The selectivity of ion transport was usually found to correlate with the potentiometric ion selectivity of the corresponding membrane electrodes [9, 10, 15, 16]. So far, virtually all experiments have concentrated on homogeneous PVC membranes.
