Application Finder
- AN-H-050Determination of sodium and potassium silicates
Determination of sodium, potassium, and silica values in sodium and potassium silicates.
- AN-H-082Determination of surface acidity in Zeolites and other materials with a high specific surface area
This Application Note outlines the determination of total acidic active surface sites in zeolites with thermometric titration.
- AN-H-083Determination of surface basicity in zeolites and other materials with a high specific surface area
This Application Note shows that the parameter of surface basicity of zeolites can be measured by thermometric titration.
- AN-H-127Thermometric analysis of aluminum by back-titration
This Application Note describes the determination of aluminum in samples containing silicon dioxide using thermometric titration and EDTA as the titrant. Excess EDTA is titrated with a Cu2+ solution of known concentration. The initial, uncomplexed Cu2+ ions react immediately with the H2O2 present in the solution, leading to a recognizable sudden increase in temperature.
- AN-T-031Na2O (free base) and SiO2 (silicate) in water glass
Determination of Na2O and SiO2 in water glass by potentiometric titration with HCl using the Sb electrode.
- AN-T-197Surface glass test according to USP<660>
The surface glass test for hydrolytic resistance combined with the glass grains test determines the glass type. The hydrolytic resistance is determined by the quantity of alkali released from the glass under specified conditions. The released alkali is then titrated with hydrochloric acid to a pH value of 5.5.
