Determination of vaginal pH by pH indicator strip and by pH micro electrode.
Vaginal pH measurement is a screening method of vaginal infection in pregnancy. We tested two different methods of pH determination. In freshly taken vaginal fluid measurements were carried out with special pH indicator strips and pH micro glass electrode. About 100 microliters of vaginal fluid is enough when pH indicator strips are used, and 200 microliters when the micro electrode is used. Th...

NIy comments will be confined to aspects of electrode construction or measuring techniquie that liffer from those originally (lescribed by Uhlich, Baldamus, and Ullriclh(l). I wislh to indlicate my deep gratittu(le to these investigators who kin(dly introduce(d me to their elegant method in 1968. The hiiglh impedlance Orion 801 amplifier witlh specially slhielded cables was used for the pH elec...
متن کاملSelective wetting-induced micro-electrode patterning for flexible micro-supercapacitors.
Selective wetting-induced micro-electrode patterning is used to fabricate flexible micro-supercapacitors (mSCs). The resulting mSCs exhibit high performance, mechanical stability, stable cycle life, and hold great promise for facile integration into flexible devices requiring on-chip energy storage.
متن کاملpH electrode performance under automated management conditions
pH is frequently measured in laboratories, but to have confidence in the results it is necessary to know that it was measured properly. For an electrode to give accurate results it must be treated well and calibrated correctly. In this paper, an automated system for pH measurement is described; the system uses the operational pH scale and calibrates using two or three buffer solutions, taking p...
متن کاملA pH Electrode Based on Melt-Oxidized Iridium Oxide
Fabrication and characterization of a novel potentiometric pH electrode based on melt-oxidized iridium oxide film is presented. The oxide film produced in a lithium carbonate melt has the composition of LixIrOy•nH2O, and shows high chemical stability. The electrode based on this oxide film exhibits very promising pH sensing performance, with an ideal Nernstian response in the tested pH range of...
