TMAH+PR+CO3

Since 2009 Rhosonics provides very accurate TMAH+PR analysers to the semiconductor industry. TMAH+PR (Tetramethylammonium Hydroxide and Photoresist) is used for the production of integrated circuits, displays and other electronic components. We have learned from our clients that it is of great value that the exact chemical composition is established . With a Rhosonics model 9570 two concentrations can be measured by using just one analyser which measures the temperature, sound speed and conductivity. By doing that the analyser can easily calculate the exact composition of the liquid. The graph gives a little explanation about how all three parameters are needed to calculate two concentrations. Dozens of installations are already integrated with our equipment. Get in touch with use to see what we can do for you.
