  • Patent number: 11441929
    Abstract: Systems and methods for sensing an amount of a liquid in a container are provided. A conduit is provided that has a length positioned relative to a portion of the container where a level of the liquid in the container changes when liquid is added to the container or liquid is removed from the container. The conduit is in fluid communication with the container to therefore allow an amount of the liquid to enter the conduit that is proportional to the amount of the liquid in the container. An outlet is provided along with a valve. The valve is in fluid communication with the conduit and the outlet, where the valve is selectable to allow the amount of liquid in the conduit to pass to the outlet, the amount of liquid passing to the outlet proportional to the amount of liquid in the container.

  • Patent number: 11428675
    Abstract: In the present system and method, a conduit from a LC device continuously transports solvent, buffers, and analytes to the inlet of a solvent removal and analyte conversion device which evaporates the solvents, leaving non-volatile analytes for detection. The device comprises a rotating disk. The liquid chromatograph device can be any device using liquid chromatography to separate molecules. The solvents in the LC effluent can include, but are not limited to, water, methanol, acetonitrile, tetrahydrofuran, and acetone. After removal of the volatile components, the non-volatile analytes are converted with a concentrated energy source so that they may be detectable.
