  • Patent number: 12270737
    Abstract: A high aspect ratio vacuum air sampling assembly is disclosed including a first canister module. The canister module includes a high aspect ratio conduit having an aspect ratio of at least 30:1, an inlet disposed at an inlet end of the conduit, and an outlet with an outlet valve disposed at an outlet end of the conduit. The outlet is in fluid communication with the inlet through an internal volume of the conduit. An air sampling train is attached to and in fluid communication with the inlet, and includes an inlet valve, a precision orifice, and a flow controller. The inlet valve and the outlet valve are configured to isolate the internal volume of the conduit from fluid communication with an external environment when the inlet valve and the outlet valve are closed. The assembly may further include a second canister module or more in sequence.

  • Patent number: 11703487
    Abstract: A gas chromatography guard column assembly is disclosed including a guard column having an inlet and an outlet. The guard column is disposed in a coil having a column coil aspect ratio of less than 15. A gas chromatography system is disclosed including an oven cavity, a heater assembly, an inlet, a guard column, an analytical column, and a detector. The guard column is in fluid communication with the inlet and is disposed in a guard column coil. The analytical column is in fluid communication with the guard column and is disposed in an analytical column coil. The detector is in fluid communication with the analytical column. The analytical column coil has an analytical column coil central axis aligned with a central axis of the heater assembly, and the guard column coil has a guard column coil central axis remote from the central axis of the heater assembly.

  • Publication number: 20150059857
    Abstract: A device for transferring and containing liquid and a mixing method are provided. The device includes a vial having at least two storage lumens extending axially along a vial body, a transfer channel coupled to a distal end of each of the storage lumens, and a common chamber in fluid communication with the storage lumens via the transfer channels. The mixing method includes providing the device for transferring and containing liquid material; providing a fluid subunit in each of the storage lumens, a distal gasket sealing each of the fluid subunits from a distal end of the vial; providing a plunger assembly coupled to a proximal end of the vial; and depressing the plunger assembly. Depressing the plunger assembly forces the distal gaskets into the gasket seats and transfers the fluid subunits into the common chamber via the transfer channels.
