Fluid Composition Analysis in Segmented Microflows via Refractive Index Measurement with Digital In-Line Holography

Year: 2025

Type: article

Abstract: , limited primarily by droplet axial positioning. Excellent agreement was observed with benchtop refractometry, demonstrating the method's suitability for monitoring two-phase process variables such as acidity in both the dispersed phase and the continuous phase. The approach holds promise for extension to absorbing media, allowing compositional analysis in complex multiphase systems under both static and dynamic conditions and is particularly relevant for advanced hydrometallurgical applications, such as nuclear fuel reprocessing and critical metal recycling.
