摘要:
An apparatus and method for chemical synthesis, the method includes accessing a recipe, the recipe including a sequence of one or more processing steps for the chemical synthesis. The processing steps including one or more steps. The recipe is executed by sorting the processing steps and executing the one or more selected steps prior to executing other steps. The chemical synthesis is monitored by providing status data, indicating a status of the execution and enabling input of control data to modify execution based on the status data or user-initiated modification. Information related to the status of the execution is displayed, typically as a graphical representation of a process action.

Methods and apparatus for facilitating the synthesis of compounds in a batch device are presented. Application of the batch type microfluidic devices to the synthesis of radiolabeled compounds is described. These methods and apparatus enable the selective introduction of multiple reagents via an enhanced rotary flow distribution valve through a single inlet port of the synthetic device. The sequential introduction of multiple reagents through a single inlet port allows an optimal delivery of highly concentrated reagents into the reactor and facilitates the synthesis of the desired products with a minimal loss of materials during transfers, which is critical to the synthesis of radiolabeled biomarkers.

Methods and apparatus for facilitating the synthesis of compounds in a nonflow-through device are presented. Application of the nonflow-through methods and microfluidic devices to the synthesis of radiolabeled compounds is described. These methods and apparatus enable the introduction of a pressurized gas through a tangential slit into a vortex reactor of the nonflow-through device, while one or more liquids are delivered to the reaction chamber through the same or different inlet ports. The introduction of the pressurized gas produces a cyclonic motion of the mixture within the reactor. Such a mechanism may be used to facilitate the evaporation of various liquids within the reactor at lower temperatures, thus reducing the production of unwanted byproducts that are associated with the use of high temperatures. In addition, thorough mixing of various liquids may be effected rapidly while allowing chemical reactions to take place efficiently within the vortex reactor.
