Indeterminate error of dilution with pipette and flask is studied based on experiments, statistics, Monte Carlo simulation and probability theory. Equations which describe the error of sample concentration after the dilution are probabilistically derived and verified experimentally and statistically. The ...
This paper will show the quantity of the measurement uncertainty from the contact angle and calculate the total measurement uncertainty for volumetric apparatus calibration.Pochaman Tagheen2010 NCSL International Workshop & Symposium: 21st Century Innovations in Metrology: RI(US).July 25-29, 2010...
We found that the other important source is the cleanliness of volumetric apparatus. With the less cleanliness, it will reduce the surface tension between the glass and liquid. The less surface tension is the more contact angle. The more contact angle is the more error of amount volume of ...
The calcium content has been determined complexometrically in a ceramic raw material at pH 12, using di-sodium salt of EDTA. The major sources of uncertainty of the results of measurement are contributions from repeatability, standardization of EDTA, volume measurement by volumetric flask, burette, ...
The lead content has been determined complexometrically at pH 4.3 using di-sodium salt of EDTA. The sources of uncertainty of the results of measurement have been identified as contributions from repeatability, standardization of EDTA, volume measurement by volumetric flask, burette, pipette and end ...
The major sources of uncertainty in the measurement have been identified as contributions from repeatability, standardization of sodium hydroxide, titration, weight of the sample taken, volume measurement by volumetric flask, burette, pipette, weighing balance etc. All major sources of uncertainty have ...
