Rhosonics inline process analyzers are widely used for wet chemical processing during the
production of TFT and Plasma screens. The entire list of applications is very comprehensive, and
we just name a few below:

• Developers, including aqueous solutions, including KOH, NaOH and many others
• Strippers
• Solvents 
• Etching liquids, such as HF, NH4F etc.
• Detergents, surfactants, etc.
• Various slurries for CMP purposes

The best solution for your chemical solutions

A list of available liquids for Rhosonics Analyzers is given below.

• NaOH, KOH - undiluted, concentration levels exceeding 30wt%
• NaOH, KOH, diluted, ranges 0.1, 0.5, 1, 2 5 and 20 wt%
• TMAH, various concentrations, i.e. 2.38 w/ or w/o PR
• IPA
• H2O2 concentration, i.e. 30% in water
• DMSO solvent concentration, MEA, etc.
• Oxalic acid
• Organic solvents, i.e. Ethanol with phosporic acid
• HF/NHF4

 Rhosonics developed special sensor systems to enable highly accurate measurements in these applications.

For NaOH, KOH, etc.: Model 8500

For TMAH/PR: Model 9570

For applications involving suspended solids: Model 9670
