About Magnetic Resonance in Emulsion Analysis

Magnetic Resonance provides a rapid, non destructive method for emulsion characterisation. Signal from the disperse phase can be measured, and the reduction in apparent diffusion co-efficient used to calculate the droplet size.

Droplet size distributions can be measured in both water oil and oil water systems. The measurement is often highly temperature sensitive, so a thermally stabilised (VT) probe is used. Strong magnetic field gradients are necessary in order to probe small droplet sizes.

The AMR R4 MR Benchtop Analyzer has special features that make it ideal for this application, including accurate sample temperature control, high strength magnetic field gradients and automated software.
