Cxli. the Technique of Glass Electrode Measurements
IN the course of an investigation into the value of the glass electrode as a means of making continuous records of the hydrogen ion concentration of circulating blood, it was found, in the preliminary experiments in which estimations were made on single samples, that there were several sources of serious error. The difficulties encountered in devising a satisfactory apparatus for measuring glas...
متن کاملGLEE, a new computer program for glass electrode calibration.
A new computer program (GLEE, glass electrode evaluation) has been written for the calibration of a glass electrode by means of a strong acid-strong base titration. This program provides an estimate of the carbonate contamination of the base, the pseudo-Nernstian standard potential and slope of the electrode and, optionally, the concentration of the base and pK(W.) The program runs under the Wi...
متن کاملPlatinum–Glass Composite Electrode for Fuel Cell Applications
Thin-film electrodes for a low-power direct methanol fuel cell DMFC were prepared by incorporating carbon-supported Pt nanoparticles Pt/C into a silicon dioxide glass matrix. The SiO2 matrix was prepared via a sol-gel technique where tetraethyl orthosilicate TEOS was hydrolyzed by H2O in the presence of methanol. The Pt/C was stirred into the sol and the resulting mixture was applied to a glass...
متن کاملElectronic Bridge for Use with the Glass Electrode *
This apparatus extends the sensitivity of an ordinary potentiometer and galvanometer so that accurate measurements can be made of the electromotive force of a cell containing a glass electrode having a resistance of about 100 megohms. The electronic bridge serves the same purpose as other circuits which have been described ;2 its advantages are good stability, high sensitivity, and moderate cos...
متن کاملDurable Phosphate Glasses with Low Glass Transition Temperatures
Phosphate glasses have special applications, but tra,ditionally never have had both durability and a low glass transition temperature (making them hard to work with). A composition study was used to find a more durable, easily fabricated phosphate glass with a low glass transition temperature. Batching, melting, casting, annealing and fabrication of test parts were performed. Glasses were chara...
