  • Patent number: 11161065
    Abstract: A liquid chromatography system, includes a fluidic flow path, a chromatography column located in the fluidic flow path, a filtration device located in the fluidic flow path before the chromatography column, the filtration device including a housing having a fluidic inlet, a fluidic outlet, wherein at least a portion of the fluidic flow path is located between the fluidic inlet and the fluidic outlet and at least one filter disposed in the portion of the fluidic flow path, wherein the at least one filter is made of a micromachined material. Liquid chromatography filtration methods are further disclosed.

  • Publication number: 20200300821
    Abstract: A removable seal device for fluidic coupling includes a seal body extending between a first end and a second end, the seal body including an inner channel configured to receive a flow of a fluid. The first end of the seal body includes a first sealing surface configured to create a first seal with a fitting sealing surface of a receiver fitting, and the seal body includes a second sealing surface configured to create a second seal with an end of a fluidic tube. The removable seal is configured to be removably secured to at least one of the fluidic tube, a support feature fixed to the fluidic tube, and a compression screw, such that untightening of the compression screw from the receiver fitting causes the removable seal device to be removed from the receiver fitting.

  • Publication number: 20180202983
    Abstract: Systems, methods, and devices for detecting leaks in chromatography systems are disclosed. The leak detection system includes a sealable compartment disposed to surround at least one component of a chromatography system. The detector is in communication, e.g., fluid communication, with an interior of the sealable compartment and configured to detect the leak by various mean including the presence of liquid or the presence of vapor, or both within the sealable compartment.

  • Patent number: 9983178
    Abstract: Described is a chromatography column assembly that includes a permanently deformable outer tube, an intermediate tube, an inner tube and a sorbent bed disposed within the inner tube. The sorbent bed may be in the form of packed chromatographic particles or a porous monolithic structure. A radial seal is provided by one or more uniform radial crimps at longitudinal locations on the assembly. The uniform radial crimp compresses the outer tube and underlying intermediate tube onto the inner tube to achieve a high pressure liquid tight seal between the three tubes. The length and depth of each crimp is accurately formed to accommodate the requirements of the particular application. Leakage along the tubing assembly is prevented and void volume is reduced or eliminated. No external ferrule or ferrule swaging mechanism is needed; therefore the chromatography column assembly is easily adapted for use in various chromatographic column configurations.
