Knowing the real corrosion potential of fuel ethanol – measuring pHe according to ASTM D6423

Knowing the real corrosion potential of fuel ethanol – measuring pHe according to ASTM D6423

Excessive acidity in alcohol based fuels accelerates engine corrosion. Total Acid Number (TAN) accounts for all titratable acids regardless of their strength and is therefore not suitable to accurately predict the corrosion potential. pHe, on the other hand measures the strength of the acids present in the sample. Therefore, pHe...

Determining the pH value of paper

Two electrometric methods for determining the pH value of papers with homogeneous and heterogeneous pH cross-sections are described. A) Paper with homogeneous pH cross-section (extraction method) This method is used for papers made in one single process that have not been subjected to any subsequent conversion process such as coating....

Automatic conductometry in water samples with low electrical conductivity in accordance with USP

Automatic conductometry in water samples with low electrical conductivity in accordance with USP 645

The USP describes a three step analysis. The first step consists of measuring the conductivity and comparing it to a conductivity limit correlated to the measured temperature. If the limit is not met, the second step is carried out. Here, the sample is tempered to 25 ± 1 °C followed by a conductivity measurement. If...
