Simultaneous measurement of particle concentration and size
Measurement of particle concentration is a ubiquitous requirement across a diverse range of applications. In many cases knowing just particle size is not enough, as sample concentration may also affect the performance of the product or the biological response to a drug delivery vector for example.
In addition, there is an increasing requirement to measure nanoparticle concentration which is being driven by the EU definition of a Nanomaterial. This definition stipulates that a sample containing 50% or more of its particles by a number distribution, with a size smaller than 100nm, may need to be identified as a nanomaterial and thus regulated as such.
There are a wide variety of applications in which the measurement of particle/nanoparticle concentration is critically important, including:
Malvern Panalytical supplies unique technologies for measuring particle concentration: Nanoparticle Tracking Analysis (NTA) and Dynamic Light Scattering (DLS).
These technologies provide concentration measurement across a wide dynamic range of concentrations and sizes, with a range of complimentary measurements also available such as particle size analysis and ensemble particle zeta potential measurement, particle mass measurement and particle fluorescence.
