A recently granted patent (Publication Number: US11833510B2) discloses a system for detecting characteristics of single partitions in a flowing series of partitions, where the partitions consist of a first fluid dispersed in a second fluid. The system includes a detector with a conduit for flowing the partitions in single file, an excitation source for supplying electromagnetic radiation to excite components within the partitions, and a detection element to detect the emitted radiation. The system also features a partitioner for generating the partitions and an optical restriction to control the amount of radiation incident on the detection element. Additionally, the system can recover a portion of the second fluid, free of the first fluid, through an apparatus connected downstream of the conduit.

Furthermore, the patent describes a method for detecting characteristics of single partitions within a plurality of partitions flowing through an interrogation region of a conduit within a detector. The method involves flowing the partitions in single file, supplying electromagnetic radiation to excite components within the partitions, and detecting the emitted radiation at a detection element. The method also includes the use of multiple excitation sources at different wavelengths, a partitioner for generating the partitions, and a reactor for initiating or modulating reactions in the partitions. Additionally, an intake system allows for the introduction of a sample into the partitioner, and an optical restriction controls the amount of radiation reaching the detection element. The method aims to efficiently detect characteristics of the partitions while ensuring minimal interference from neighboring partitions.
