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.

DelsaMax ASSIST is a cell pressurisation system which can be used in conjunction with the DelsaMax PRO light scattering analyser. The PRO, you may recall, can be used for particle characterisation in which both particle size and zeta potential (otherwise known as electrophoretic mobility) are to be measured. Incredibly, it can determine these factors simultaneously in less than one second.

To make life even easier for the analyst, the PRO can be fitted together with the ASSIST to put the liquid sample in the cell under pressure. This reduces the problem of bubbling and interference, and thus prepares the particle suspension for trouble-free analysis.

For convenience, the design of the DelsaMAX ASSIST allows it to be stacked neatly underneath the PRO. They can be neatly ‘plumbed’ together via the PRO’s front panel or its top panel door.

Whether you are using the DelsaMax PRO or the DelsaMax CORE analyser, you will benefit from the DelsaMax Analysis Software which has been specially created to maximise their benefits.

With the help of this software, the processes of collecting data, analysing it and interpreting the physical characteristics of the particles in solution are streamlined. It provides an unbeatably reliable platform for individual sample analysis over a wide temperature and laser intensity range.

Users are sure to welcome its intuitive interface, its fully customisable autocorrelation analysis function and its unique ‘normalisation’ algorithm feature. Its outputs include precise distributions, overlays, customer use variables and reports.
