US Patent:

20180321197, Nov 8, 2018

Filed:

Jul 16, 2018

Appl. No.:

16/036548

Inventors:

- Sunnyvale CA, US
Glenn M. KUSE - Pleasanton CA, US
Rong LIN - Santa Clara CA, US
Sheetal BHARDWAJ - Fremont CA, US

International Classification:

G01N 30/02
G01N 30/92
B01D 15/36

Abstract:

An apparatus for detecting analytes in a liquid sample may include an elongated primary channel through which an ionic species flows, the primary channel extending through a primary channel member, a first regenerant channel through which a regenerant flows, the first regenerant channel extending adjacent to the primary channel and being formed in a first block, a first charged barrier having exchangeable ions capable of passing ions of only one charge, positive or negative, and of blocking bulk liquid flow, the first charged barrier disposed between the primary channel member and the first block for separating the primary channel from the first regenerant channel, and a first sealing member disposed between the first charged barrier and the first block defining the first regenerant channel.

Appl. No.:

14/587780

Inventors:

- Sunnyvale CA, US
Rong LIN - Sunnyvale CA, US
Christopher A. POHL - Union City CA, US
John Edward MADDEN - Sunnyvale CA, US

International Classification:

B01J 20/281
B01D 15/36
B01D 15/08
B01D 61/52
B01D 61/46

Abstract:

An apparatus for treating an aqueous sample stream includes analyte ions. The apparatus comprises an ion exchange barrier; a sample stream flow channel; an ion receiving stream flow channel adjacent to the sample stream flow channel and separated therefrom by said first ion exchange bather. Stationary flow-through ion exchange packing is disposed in the sample flow channel of the same charge as the ion exchange bather. The ion exchange packing comprises a mixture of a first ion exchange portion with strong ionizable groups and a second ion exchange portion with weak ionizable groups of the same charge. First and second electrodes are in electrical communication with the sample stream flow channel and ion receiving flow channel.

Appl. No.:

14/097638

Inventors:

- Sunnyvale CA, US
Sheetal BHARDWAJ - Fremont CA, US
Rong LIN - Santa Clara CA, US

Assignee:

DIONEX CORPORATION - Sunnyvale CA

International Classification:

B01D 53/32

Abstract:

An electrolytic device, e.g. a suppressor, including at least two flow-through channels separated by a charged membrane barrier, and a catalyst, for combining hydrogen and oxygen gas, together with ion exchange material, disposed in one of the channels. Also, a method for simultaneous electrolysis and catalytic gas elimination in a channel of the device is described.

International Classification:

G01N 30/96

US Classification:

436161, 204242, 205464, 2101982

Abstract:

An electrolytic device comprising: a central sample flow channel, first and second regenerant flow channels, first and second charged barriers disposed between said sample flow channel and first and second regenerant flow channels, and pairs of oppositely charged, spaced electrodes disposed in the regenerant flow channels. Also, electrolytic devices with a different electrode configuration are described. Also, methods of using the devices, e.g., for suppression in an ion chromatography system are described.
