The Use of Focused Aerosol Deposition in the Collection and Analysis of Nanoparticles from Ultrapure Water Systems Used in Semiconductor and Pharmaceutical Industry

Van Schooneveld G., Keady P., Oberreit D., CT Associates, Inc, US

The reduction of particles in ultrapure water (UPW) systems is driven primarily by the semiconductor industry. Particles that can produce defects in chip manufacturing and potentially reduce yield, are now identified to be 10 nm [...]

A Novel Method for Measuring the Sizes and Concentrations of 5-500 nm Particles in Colloidal Suspensions

Van Schooneveld H.G., Litchy M.R., Grant D.G., CT Associates, Inc, US

A new measurement technique has been developed that allows for measurement of particles as small as 5 nanometers in colloidal suspensions. The technique has demonstrated the ability to provide unique and useful particle size distribution [...]
