Support & service (93)- AN-H-129AN-H-129Determination of weak bases in nonaqueous media through catalyzed thermometric endpoint titration (CETT)
Weak, organic bases that are soluble in nonaqueous solvents (including nonpolar solvents) are determined in glacial acetic acid using titration with strong acids, e. g., anhydrous perchloric acid or trifluoromethanesulfonic acid. The endpoint of such titrations can be determined thermometrically, insofar as a suitable thermometric endpoint indicator exists. The exceptional suitability of isobutyl vinyl ether (IBVE) as indicator has been demonstrated.
- AN-H-130AN-H-130Determination of nitrite using sulfamic acid
This Application Note describes the determination of nitrite using thermometric endpoint titration with sulfamic acid. The nitrite content of a solution can be analyzed down to 0.2 mmol/L.
- AN-H-131AN-H-131Determination of titer and blank value for thermometric titrations using tiamo™
This Application Note describes in detail how to determine the blank value and the titer for thermometric titrations using tiamo™.
- AN-H-132AN-H-132Thermometric endpoint titration of hydrogen peroxide with iodometry
Hydrogen peroxide solutions can be determined through thermometric endpoint titration (TET) using iodometry. Iodide is oxidized to become iodine, which is then titrated with a standard thiosulfate solution in an exothermic reaction.
- AN-H-133AN-H-133Automatic sodium determination in cheese
Sodium can be determined thermometrically in cheese without sample preparation and addition of additives. A homogenizer is responsible for distribution and stirring. In addition to this application note, you can find more information on thermometric sodium determination in foods in our application video available on YouTube: https://youtu.be/lnCp9jBxoEs
- AN-H-134AN-H-134Determination of sulfuric acid and phosphoric acid in etching baths using thermometric titration
Thermometric titration can be used for the ready determination of sulfuric acid and phosphoric acid in acid mixtures. An endpoint for each acid appears on the titration curve that can be used to quantify the respective acid.
- AN-H-135AN-H-135Determination of hydrochloric acid and phosphoric acid in etching baths using thermometric titration
Thermometric titration is used for the determination of hydrochloric acid and phosphoric acid in acid mixtures. Two endpoints appear on the titration curve that are used for the determination of the two acids.
- AN-H-136AN-H-136Determination of hydrochloric acid and nitric acid in etching baths using thermometric titration
Thermometric titration is used for the determination of hydrochloric acid and nitric acid in acid baths. The entire acid content is titrated with caustic soda in the initial titration; the hydrochloric acid content is then determined in a second titration using silver nitrate solution.
- AN-H-137AN-H-137Determination of hydrochloric acid and hydrofluoric acid in etching baths using thermometric titration
Thermometric titration is used to determine hydrochloric acid and hydrofluoric acid (hydrogen fluoride) in etching baths containing ethanol and acetonitrile. Two endpoints appear on the titration curve that are used individually for the quantification of the respective acid.
- AN-H-138AN-H-138Determination of nitric acid and hydrofluoric acid in etching baths using thermometric titration
Thermometric titration is used to determine hydrofluoric acid and nitric acid in etching baths containing ethanol and acetonitrile. Two endpoints appear on the titration curve that are used individually for the quantification of the respective acid.
