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

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.

Studying Fat Globules in Milk

Milk

The following article, based on application information available via the Beckman Coulter website, gives an example of how measurements of particle size and zeta potential may both be obtained using the same instrument. In this case the subject is fat globules in homogenised milk. Continue reading Studying Fat Globules in Milk
