Glass beads - particle size distribution

Description

• General description: This Standard Reference Material (SRM) is intended for use in the evaluation and calibration of equipment used to measure particle size distributions (PSD) in the 2 μm to 12 μm diameter range. Typical methods for PSD determination would be laser light scattering (LLS), electrical sensing zone (ESZ), and sedimentation. A unit of SRM 1021 consists of a single bottle containing approximately 4 g of solid spherical soda-lime glass beads. For more information, please refer to the SDS and COA.SRM 1021_certSRM 1021_SDS
• Other Notes: Please download a current certificate at nist.gov/SRM for current analytes and certified values.
