A. Features 1. Automatic measurement of concentrated liquid dispersions (emulsion, suspension, foam) stability without dilution using multiple light scattering technology 2. Vertical scanning via reading head consisting of pulsed near infrared light source and two synchronous transmission & backscattering detectors 3. Qualitative and quantitative monitoring capabilities of dispersions evolutions as the time elapses and temperature changes 4. Determination of the instability phenomena such as particle size variation (coalescence or flocculation) and particle migration (creaming or sedimentation) 5. Characterization of dispersions evolutions parameters: Backscattered (BS) and transmitted (T) light flux, l/l* (photon mean free path), Φ(volume fraction), s (specific surface), l (mean distance between particles) 6. Characterization of dispersions evolutions kinetics: BS & T variations, phase thickness, particle migration velocity, hydrodynamic diameter, l/l*, Φ, s, l versus time 7. A variety of applications from a simple stability control to a quantified analysis 8. One acquisition every 40m along the whole sample height for high vertical resolution and fast measurement within 20 seconds per scan 9. Data acquisition in "scan" mode and "fixed position" mode with multi-step programmable acquisition interval and duration of analyses 10. Easy sampling and preservation of the tubes to temperature up to 100°C, to centrifugation up to 2000G, and to autoclave 11. Automatic sample tube recognition with bar code reader available 12. Global stability kinetics and stability index for easy comparison available 13. Wide temperature control range from +4°C to 60°C for test under severe conditions |
