WATERS TECHNOLOGIES CORPORATION - Milford MA
International Classification:
G01N 1/10
US Classification:
422501
Abstract:
Described is a compound sample needle for a liquid chromatography system. In one embodiment, the compound sample needle includes a rigid needle having a coupling end with a face and a counterbore. The compound sample needle also includes a flexible tubing having an outer surface and a coupling end disposed in the counterbore of the rigid needle. The coupling end of the flexible tubing has a face adjacent to a base of the counterbore. The coupling ends of the rigid needle and flexible tubing are secured to each other by a weld formed along a circumference of the outer surface and the face of the rigid needle. A rigid sleeve protects the welded joint. The compound sample needle is suitable for injection into the high pressure mobile phase of ultra performance liquid chromatography systems.

Assignee:
WATERS TECHNOLOGIES CORPORATION - Milford MA
International Classification:
F16K 5/00
US Classification:
251304, 2989012
Abstract:
A valve includes a rotor and a stator. The rotor and the stator each have seal surfaces for contacting and sliding against one another during operation of the valve. Either or both of the rotor and the stator have a seal-surface coating formed by depositing an at least partially amorphous interlayer on a substrate and depositing a surface layer, including diamond-like carbon, the interlayer. The surface layer requires no mechanical polishing.

Device And Methods Using Porous Media In Fluidic Devices
US Patent:
2018002, Jan 25, 2018
Filed:
Sep 12, 2017
Appl. No.:
15/702007
Inventors:
- Milford MA, US

International Classification:
B01L 3/00
G01N 30/60
G01N 30/60
Abstract:
A system that incorporates teachings of the subject disclosure may include, for example, a process that includes obtaining a porous medium comprising a porous material having a first shape and an initial porosity profile. The porous medium is engaged with a cavity in a fluidic device, wherein the cavity is in fluid communication with a channel of the fluidic device. The first shape of the porous material can be adjusted to a second shape resulting in the initial porosity profile being adjusted to a target porosity profile. Such adjustment can be accomplished by the engaging of the porous medium with the cavity, by pre-adjusting a shape of the porous media before insertion into the cavity, or by some combination thereof. Other embodiments are disclosed.

F16K 11/085
B29C 45/56
F16K 11/085
Abstract:
A shear valve assembly for use in a high performance liquid chromatography system. The shear valve assembly includes a stator having a plurality of first fluid-conveying features; and a rotor having one or more second fluid-conveying features. The rotor is movable, relative to the stator, between a plurality of discrete positions such that, in each of the discrete positions, at least one of the one or more second fluid-conveying features overlaps with multiple ones of the first fluid conveying features to provide for fluid communication therebetween. The rotor, including the second fluid-conveying features, is formed by injection-compression molding.

Robert A. Jencks - Mendon MA, US
Assignee:
WATERS TECHNOLOGIES CORPORATION - Milford MA
International Classification:
F16K 5/00
US Classification:
251304
Abstract:
A rotary shear valve assembly for liquid chromatography applications comprises a rotor assembly having a rotor and a drive shaft with a head portion. The rotor has a substantially planar surface with one or more rotor grooves and a pair of holes. The head portion has two pins. The pins are disposed substantially diametrically opposite of each other on a line through a center of the head portion. Each pin mates with one of the holes in the rotor. The rotor assembly can further comprise means for urging the rotor surface against the stator surface such that each rotor groove aligns with and provides a fluidic channel between two of the stator openings.
