This is a composite pH electrode equipped with a double junction system for pH measurement in non-aqueous solvents (for example, pH in ethanol). There is also a version available with a pt1000 for simultaneous temperature measurement (600235600).

This analysis is conducted in accordance with the EN ISO 3657 standard and is based on modifications of the AOAC 920.160, ASTM D5558, USP <401>, and Ph.Eur. 2.5.6 guidelines. By using potentiometric indications, it is possible to obtain very accurate results for a wide range of edible oils and animal fats, as well as for waxes and other products with a high saponification value.

This application note describes the non-aqueous perchloric acid titration of amines. Specifically, the concentration of triethanolamine (TEA) is measured by titrating with perchloric acid in a glacial acetic acid solvent, using Solvotrode easyClean and lithium chloride-ethanol as the electrolyte (internal liquid of the electrode).

This is a composite pH electrode equipped with a double junction system for pH measurement in non-aqueous solvents (for example, pH in ethanol).

Electrode tip for micro pH measurement with a diameter of 6.4 mm.

This explains the measurement of copper and zinc in brass plating baths, free cyanide, ammonia, carbonates, copper and tin in bronze plating baths, and free cyanide.

In titration using the OptoRoad M2, a sensor for photometric titration, it has been demonstrated that the recovery rate for rare earth elements is approximately 100%, achieving high accuracy and excellent reproducibility.
