Near infrared sensor setup for general interface detection in automatic liquid-liquid extraction processes

This work presents a novel sensor setup for the general detection of liquid-liquid interfaces in different mixes liquids as part extraction device. The is applied to laboratory scale separatory funnel. It uses near infrared array which receives light going through inside funnel, are illuminated by source located on other side and below Light refracts funnel reflects interface creating changing patterns intensity measured sensor, providing way locating interface. Liquid with optical features, from transparent opaque, emulsion clean, used test whether types produce distinguishable response allowing detect situations that can occur an Artificial Intelligence orchestrated battery chemical synthesis process. Emulsion create discernible change input lowering registered when crossing front making them easier locate than techniques. opens possibility detecting it forming be miniaturized attached funnels manual aid or vessels automatic solutions like liquid handling robots pipetting robots.
