Application Memo Quantification of TMAH Industry Inorganic chemical industryInstrument Automatic potentiometric titratorMeasurement method Acid-base titration Standards 1.Overview TMAH (tetramethyl ammonium hydroxide) is measured by titration with 0.1mol/Lhydrochloric acid after the test sample is diluted with water. The endpoint is determined byLevel Stop which is previously selected and preset in the titration system. The concentrationof TMAH is calculated from the titration volume of hydrochloric acid solution. 2. Apparatus Main unit Automatic potentiometric titrator (preamplifier STD) Electrode pH glass electrode Ceramic reference electrode Temperature compensation electrode 3.Reagents Titrant 0.1mo1/L hydrochloric acid solutionSolvent Pure water 4.
