Evaluation of Uncertainty in Nanoparticle Size Measurement by Differential Mobility Analysis

Lin C-M, Yu T.-C., Lai S.H., Ho H.C., Weng H.F., Wang S-H., Chen C-J., Center for Measurement Standards, Industrial Technology Research Institute, TW

This paper presents the measurement results and the uncertainty analysis for four batches of polystyrene latex (PSL) spheres with nominal sizes of 20 nm, 100 nm, 300 nm and 500 nm using the measurement system [...]

Evaluation of Uncertainty in Nanoparticle Size Measurement by Electro-gravitational Aerosol Balance

Lin C-M, Yu T.-C., Pan S.-P., Wang H.-F., Chen C-J., Industrial Technology Research Institute, TW

A primary standard of particle size ranging from 100 nm to 500 nm in number mean diameter, based on the electro-gravitational aerosol balance, has been developed in Center for Measurement Standards of Industrial Technology Research [...]

Nanoparticle Measurement by Spectroscopic Mie Scattering

Trutna R., Liu M., Chamberlin D., Hadley J., Agilent Technologies, US

We present a spectroscopic technique for measuring particle size. The technique utilizes a UV-Visible spectrophotometer to measure the attenuation spectrum of a particle dispersion due to scattering. Using the Mie scattering theory, we compute the [...]
