/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".
