ASTM Publishes E2834 Standard Defining Nanoparticle Tracking Analysis
SALISBURY, England, July 3, 2012/PRNewswire/ --
NanoSight is delighted to welcome publication of American Society of Testing Materials
ASTM E2834 - Standard Guide for Measurement of Particle Size Distribution of Nanomaterials
in Suspension by Nanoparticle Tracking Analysis (NTA).

This document details application of Nanoparticle Tracking Analysis (NTA) to
measurement of particle size distributions for suspended particles from ~10nm to the onset
of sedimentation.
Duncan Griffiths, NanoSight's USA West Sales Manager comments "This document has taken
almost three years to develop. It provides a rigorous review of the core science driving
Brownian motion and the derived parameters of mean, mode, percentile values and
concentration. The scrutiny of demanding third-party experts has been fundamental in
producing a thorough appraisal of NTA. The result is a meticulous presentation of science
and methodology. We are delighted".
The UK's National Physical Laboratory (NPL) has seen NanoSight develop NTA since its
early days more than five years ago. Helen Sharman from NPL comments: "NPL has been
working on the characterization of nanomaterials for many years, in-part collaborating
with NanoSight. The nanomaterials team has followed the development of the NTA technique
with great interest due to its unique capability in the area of nanometrology. As the UK's
national measurement institute, NPL recognizes the importance of this standard and the
capability of the NanoSight instrumentation to provide consistent, precise and comparable
data."
NanoSight CEO Jeremy Warren adds "Whilst this standard is a milestone, it is also a
building block. Many NanoSight users have requested this definition of the technique as
they present data in research papers and to regulatory bodies for product approvals and
clinical trials. We will now move to provide industry with test methods for specific
materials to help lock down SOPs. The timing of this publication is helpful as the
European Commission move to consider methodologies to address the characterization
challenges of their recently-published definition of nanomaterials. Here we see a
significant role for NTA's unique nanoparticle counting capability".
The Standard is available from ASTM at http://www.astm.org/Standards/E2834.htm
