  • Publication number: 20240060939
    Abstract: A method and a fluidic network for acquiring and injecting a chromatographic sample into a chromatography system flow include a metering pump module, a sample needle, a needle seal and an injection valve. The metering pump module includes a metering pump and a pressure transducer in serial fluidic communication. When the injection valve is in a first valve state, the injection valve is configured to fluidically terminate ports of the metering pump module. When the injection valve is in a second valve state, the injection valve is configured to fluidically couple a fluidic path that includes the metering pump module and sample needle into the system flow of a chromatography system without resulting in a substantial change in the pressure of the system flow.

  • Publication number: 20240025858
    Abstract: The present invention relates to a group of novel compounds, methods for their manufacture and the use of these compounds as research tools and as pharmaceuticals. The novel compounds are analogues of cannabidiol (CBD). CBD is a non-psychoactive cannabinoid which has been used to treat various diseases and disorders. While such treatments hold promise, there remains a need in the art for more effective treatments and this has been brought about by way of novel cannabidiol compounds.

  • Patent number: 11853763
    Abstract: A new device executing an application on a new central processing unit (CPU), determines whether the application is for a legacy device having a legacy CPU. When the new device determines that the application is for the legacy device, it executes the application on the new CPU with selected available resources of the new device restricted to approximate or match a processing behavior of the legacy CPU, e.g., by reducing a usable portion of a return address stack of the new CPU and thereby reducing a number of calls and associated returns that can be tracked.

  • Patent number: 11774415
    Abstract: Described is a metering pump that may be used to meter volumes of sample in a chromatography system. The metering pump has a modular configuration that allows for separation of a head pod from a drive assembly for easy serviceability. The head pod includes a pump head, cartridge housing, seal wash housing and plunger. The drive assembly can be implemented in an inline drive configuration. Alternatively, the drive assembly can be implemented in an offset drive configuration in which a stepper motor is displaced laterally from other drive assembly components but is coupled through a belt and pulley system.
