About This Item
ASTM E2834 is the ASTM standard guide for measuring particle size distribution of nanomaterials in suspension by nanoparticle tracking analysis (NTA). It provides a structured reference for evaluating dispersed nanoscale particles in a liquid medium, helping users apply a consistent approach to measurement and reporting. For laboratories, manufacturers, and technical teams working with nanomaterial suspensions, this standard supports more reliable comparison of results and better alignment around a common testing method.
What is ASTM E2834?
This standard guide describes a technical framework for measuring particle size distribution in nanomaterials that are suspended in liquid using nanoparticle tracking analysis. ASTM E2834 is intended to help users understand how NTA can be applied to characterize particles in suspension in a consistent, repeatable way. As a guide rather than a prescriptive test method, it is generally used to support informed measurement practices, data interpretation, and reporting for nanoscale materials.
Where is ASTM E2834 used?
ASTM E2834 is commonly used in laboratory and quality-focused settings where nanomaterials in suspension need size distribution analysis. It is relevant to researchers, product developers, and testing groups working with nanoparticle dispersions or similar liquid-based samples. The standard may also be used when selecting or validating nanoparticle tracking analysis workflows, helping ensure that measurements are performed and reported in a way that supports technical review, comparison, and repeatable evaluation.
Why is ASTM E2834 important?
This standard matters because particle size distribution can strongly affect how nanomaterials behave, perform, and are compared across datasets. ASTM E2834 helps bring consistency to NTA-based measurement practices, which can support quality control, product evaluation, procurement decisions, and compliance-oriented documentation. By using a recognized ASTM guide, organizations may reduce ambiguity in reporting and improve confidence in the results used to assess suspended nanomaterials.
