Nanoparticle Analysis Made Simple

In recent months the Dynamic Light Scattering website has gone into considerable detail on the principles by which this method gives us information on particle size. I would now like to simplify things and talk about what the Beckman Coulter DelsaMax family of dynamic light scattering instruments actually does to make life easier for those involved in particle characterisation.

Flow cytometry - Beckman Coulter

Having written a lot about Beckman Coulter’s contribution to the field of dynamic light scattering, a recent news item has reminded me that there is a lot more to the company than the manufacture of particle characterisation instruments. The report concerned the acquisition of a specialist developer and maker of cytometers. Continue reading Cytometry

DelsaMax ASSIST and Analysis Software

DelsaMax ASSIST - Beckman Coulter


In some of my recent posts I have given brief details of the DelsaMax PRO and CORE dynamic light scattering instruments from Beckman Coulter. Among other things, I have been amazed by how quickly, accurately and reliably this series delivers its particle size and zeta potential analysis. I have also been impressed by the fact that it can do this with incredibly small samples and tiny particles. Today I’d like to talk about the other two items in the DelsaMax product line-up: DelsaMax ASSIST and the DelsaMax Analysis Software. Continue reading DelsaMax ASSIST and Analysis Software

DelsaMax PRO and CORE Analysers

DelsaMax CORE – Beckman Coulter

DelsaMax CORE

Depending on your specific particle characterisation needs, the main choice you will need to make within the new DelsaMax range of dynamic light scattering instruments from Beckman Coulter might well be between the PRO and CORE versions. A little summary here might help. Continue reading DelsaMax PRO and CORE Analysers

I’m always interested to know something about the background of companies who make the instruments I use. In the case of Beckman Coulter, which makes dynamic light scattering equipment, there is a lot of information to research. Particle characterisation is just one of many areas in which this organisation supplies products and services. Even within that category, the photon correlation spectroscopy (for measuring sizes and size distributions) and electrophoretic light scattering (for measuring zeta potential) instruments are not the only ones on offer.

If you are a regular reader of the dynamic light scattering website, or of those on Coulter Counters ( and pore size (, you will probably be aware of Meritics ( Meritics provides authoritative advice and support on these and all other aspects of particle and material characterisation technology.

New DelsaMax Series of Analysers


This month I have information on a whole new series of dynamic light scattering instruments from Beckman Coulter. The DelsaMax Series looks set to take nanoparticle research to another level in terms of speed, accuracy and reliability. Continue reading New DelsaMax Series of Analysers
