The new Droplet Size Analyser 2.0 introduces a completely new user interface, GoScan for Minispec, with the possibility to characterize multimodal droplet size distributions and further imporve the results for unimodal distributions where a lognormal shape is assumed.
- Standard TD-NMR system for the determination of the oil and water droplet size distribution in emulsions (oil-in-water: Mayonnaise; water-in-oil: Margarine, Diet Spreads and related products) running the new G-Var method.
The minispec mq-Series are flexible TD-NMR Analyzers and can potentially also be used for other applications, of course depending upon system configuration. The minispec mq20 oil & water droplet size analyzer, accommodates sample tubes of 10 mm outer diameter and can also be utilized for diffusion and relaxation time measurements. It consists of:
