By employing a series of phase sensors and a dedicated algorithm to detect the passage of a reaction slug, the reactor can efficiently track the position of the reaction slug within the platform (Figure ). This cost-effective approach enables precise control over the reaction as it traverses the system. The ability to accurately monitor the reaction's location throughout eliminates the need to hardcode pump volumes, allowing for seamless compatibility with reactors of varying sizes without requiring any code modifications. Moreover, this tracking capability facilitates precise "parking" of the reaction slug in the NMR for analysis, optimizing reagent usage by minimizing the required quantity for each reaction condition.
