UltraChem® 40 Liquid Particle Counter Highly reliable particle counter with 40 nm sensitivity for high molecular scatter applications Your products need reliable contamination monitoring. You need to detect the smallest particle possible. Now get both – sensitivity to 40 nm particles with the greatest reliability available on the market. If your application requires measuring small particles in chemicals with high molecular scatter, UltraChem® 40 is the best tool for the job. NanoVision Technology® eliminates the competition between the light scattered by fluid molecules and particles. This makes 40 nm sizing possible for the first time. Background and false counts are a thing of the past. The NanoVision Technology breakthrough ensures only information that matches a particle fingerprint is counted. The result: Data you can act on with confidence. BENEFITS Detect Small Particles • 40 nm sensitivity • Large sample volume for improved data quality NanoVision Technology® • Adaptive technology makes the instrument immune to most optical contamination • See what your particle counter sees • Measures small particles in a wide range of chemicals, including high molecular scattering fluids. Chemicals include: • PGMEA • Photoresist solvents • HF • Sulfuric acid Low Cost of Operation • 3-year warranty on Liquid Particle Counter 1-year warranty on Electronic Flow Controller • Solid state laser diode • Simple design Versatile • Online or batch sampling capabilities • Multiple communication protocols • Small footprint allows placement in various locations DI water monitoring (cold and hot) Chemical distribution monitoring Chemic
