Title: Screening Candidates for 30 nm Spheres
Published: August 01, 2006
Abstract: This paper describes the preliminary screening process that was conducted to identify potential candidate particles to be used as the NIST Standard Reference Material (SRM) 30 nm spheres. Five different samples were obtained and measured using the NIST particle calibration facility. The sample with the most narrow size distribution and a preliminary peak particle diameter of 30.1 nm was identified as a potential candidate to become the NIST 30 nm SRM. A secondary candidate, with a fairly narrow distribution and a peak particle diameter of 24.2 nm was also identified. Further studies to address accuracy issues and ensure repeatability are recommended.
