    摘要: Methods and devices for a fully automated synthesis of radioactive compounds for imaging, such as by positron emission tomography (PET), in a fast, efficient and compact manner are disclosed. In particular, the various embodiments of the present invention provide an automated, stand-alone, hands-free operation of the entire radiosynthesis cycle on a microfluidic device with unrestricted gas flow through the reactor, starting with target water and yielding purified PET radiotracer within a period of time shorter than conventional chemistry systems. Accordingly, one aspect of the present invention is related to a microfluidic chip for radiosynthesis of a radiolabeled compound, comprising a reaction chamber, one or more flow channels connected to the reaction chamber, one or more vents connected to said reaction chamber, and one or more integrated valves to effect flow control in and out of said reaction chamber.

    摘要: 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.

    摘要: Methods and apparatus to assess current aspects of Quality Control useful for release of radioactive compounds for imaging, such as PET tracers as injectables, in an automated manner, without user interference, and in compliance with regulatory guidelines. The present method and system relates to an integrated automated quality control analysis of a substance utilizing a single sample injection for a plurality of inline quality control tests. A quantitative analysis of the sample via the plurality of quality control tests is conducted. A measurement value of each of the plurality of quality control parameters is determined and a comparison of each measurement value of the plurality of quality control parameters with a predetermined corresponding criterion value is made. A cumulative quality rating for the sample is determined and the validated sample is released based on the quality rating.
