- Abstract:
- This study is aimed to determine proper measurement parameters and procedures for accurate DLS measurement in determining the size of nanoparticles in a solution. We evaluated the effect of dust limit, upper dust limit and accumulation number on the relative repeatability uncertainty of DLS size measurement. Our proposed protocol reduced the relative repeatability uncertainty of size measurement down to 5% for suspension of gold nanoparticle (AuNP).
