Inter and intraday precision were less than %12.2 in terms of RSD. Phosphates and pH were determined simultaneously in different eye drops and the results were validated using reference method such as potentiometry (pHmeter) and ion chromatography....
The best peaks parameters (height and area, repeatability, and resolution) were obtained using phosphate-borate buffer. Then, the concentration and pH of this buffer were optimized. Optimization of the concentration and pH of BGE The influence of BGE concentration on the height, area and shape ...
pH selective electrode connected to a decimilivoltimeter; Cl − SE: Chlo- ride selective electrode connected to a decimilivoltimeter; Ref.: reference AgCl/Ag electrode; W: waste. internal diameter was used for connections. The holding coil ...
Thus, the equivalence point can be determined either potentiometrically (using a pH meter) or simply with an acid-base indicator. Three nontoxic mediators (phosphate, EDTA, and sulfite) were tested, and optimal conditions for the sharpest pH changes were sought. A combination of phosphate (a ...
pH measurements were carried out with a Jenway pH-meter model 3505. 2.4. Electrode Preparation Carbon paste electrode was prepared by hand mixing accurately weight (500 mg) of highly pure graphite powder and plasticizer (0.2 mL of DOP, TCP, DBP, DOS, or o-NPOE) using an agate ...
initial rate calorimetry (IrCal), for obtaining the initial reaction rates using isothermal titration calorimetry (ITC) (Fig. 1), which is a very sensitive calorimetric method and has been widely applied in chemistry and biology for measuring thermodynamic param- eters of a ligand binding to ...

The pH of samples was measured using a pH meter (ORION 5 star, Thermo Scientific, Canada). The absorbance of the samples was measured and recorded in the range of 190–800 nm. 3. Results and discussion 3.1. Determination of optimum polymer dose with conventional tests CST test was used ...
The operating conditions of the ICP-OES equipment are listed in Table 2. The pH was determined using a portable pHmeter (ORION RESEARCH, INC., Orion 230 A, Beverly, MA, USA) equipped with a 9107 BN Orion glass electrode. For sorption of the analyte, a minicolumn (85 mm length × ...
