HORIBA is proud to introduce the HD-960L Dissolved O2 monitor for HF and other acids (e.g. Citric Acid). Leading edge device manufacturers are increasingly using low O2 chemicals to prevent galvanic corrosion on Cu and other metals in both BEOL and FEOL applications. The HD-960L utilizes Membrane Polarography technology to provide an effective method to monitor the O2 level present with sub ppb level resolution.
