ARM - Based Automatic Potentiometric Titration System
Accurate measurement and analysis are very important tasks for many applications ranging from industrial operations, analytical laboratories to biological processes. In modern analytical chemistry, automatic titrators have more prominence than manual interpretations. Various instruments have been developed and proposed in the past to carry out potentiometric titrations. Also there are suppliers...
متن کاملPotentiometric titration and conformational change in pepsinogen.
Potentiometric titrations of pepsinogen as functions of ionic strength and temperature were studied. It was found that the ionic strength has a minor effect on the titration behavior of the protein. The maximum values of the buffering capacity in the pH range of 6.0 to 9.0 were found at pH values corresponding to those at which a conformational change of the protein occurs as determined by opti...
متن کاملA Convenient Method for Potentiometric Titration of Chloride Ions
A convenient reference cell and method of potentiometric determination of chloride ions with silver nitrate is described. The method is accurate to about +/- 0.02 ml. 10(-4)M silver nitrate.
متن کاملA Student-Designed Potentiometric Titration: Quantitative Determination of Iron(II) by Caro's Acid Titration
Oxidation–reduction titrations and potentiometric methods provide a convenient experimental means to quantitatively determine compositions of unknown mixtures containing oxidizable/reducible species. Over the past decade, numerous titration methods have appeared in this Journal (1–6) and in standard laboratory manuals (7–10) involving common titrants such as potassium dichromate, iodine, potass...
متن کاملZn(2+)-heparin interaction studied by potentiometric titration.
Measurement of the decrease in pH that accompanies the addition of Zn2+ to heparin in solution provided an indirect method of examining cation-polyanion interaction. Construction of plots analogous to isothermal saturation binding plots revealed the existence, for defined conditions of interaction, of a [heparin]-independent direct proportionality between the fraction of the maximal pH change o...
