Lithium Ion-Selective Electrode For Clinical Applications

View page
US Patent:
6508921, Jan 21, 2003
Filed:
Mar 24, 2000
Appl. No.:
09/534464
Inventors:
Xihai Mu - Chino Hills CA
Chandra P. Jain - Placentia CA
Assignee:
Beckman Coulter, Inc. - Fullerton CA
International Classification:
G01N 27333
US Classification:
204418, 21050028, 21050027
Abstract:
A lithium ion-selective membrane that favors the bonding of lithium and depresses sodium interference is invented by a charge balance approach. A lithium ion-selective electrode (Li-ISE) having the membrane of this invention demonstrates a fast kinetic response, good precision and reproducibility, high sensitivity and the ability to retain the sensitivity after a long-term contact with biological samples. The sensor shows Nernst linearity with a slope of 55. 4 mV for lithium ion concentrations between 0. 5 mol/L and 10 mmol/L. The membrane includes at least about 2% by weight of 6,6-dibenzyl-1,4,8,11 tetraoxacyclotetradecane ionophore; from about 0. 025% to about 1% by weight of potassium tetrakis(4-chlorophenyl)borate additive; a plasticizer; and a polymeric material.

Assay System With In Situ Formation Of Diazo Reagent

View page
US Patent:
20050266579, Dec 1, 2005
Filed:
Jun 1, 2004
Appl. No.:
10/858673
Inventors:
Xihai Mu - Chino Hills CA, US
Rose Cernosek - Placentia CA, US
International Classification:
G01N033/00
US Classification:
436097000, 436166000, 422061000
Abstract:
A total bilirubin diazo assay is disclosed in which an acidic solution containing a primary aryl amine is combined directly with a nitrite-containing sample solution at approximately neutral pH, resulting in the in situ generation of a diazo compound in the sample solution. The diazo compound reacts with bilirubin in the sample solution to form a colored reaction product that can be measured.

Potentiometric Measurement Of Chloride Concentration In An Acidic Solution

Appl. No.:
10/931096
Inventors:
Xihai Mu - Chino Hills CA, US
International Classification:
G01N 27/26
G01F 1/64
US Classification:
205775000, 204416000
Abstract:
Measuring chloride ions in a sample solution at acidic pH with a potentiometric silver chloride electrode is disclosed.

Diluent And Method For Determination Of Total Calcium

View page
US Patent:
54242142, Jun 13, 1995
Filed:
Oct 27, 1993
Appl. No.:
8/144928
Inventors:
Frank R. Shu - Hacienda Heights CA
Xihai Mu - Chino Hills CA
Suzanne C. Chung - Brea CA
Peter J. Houben - Yorba Linda CA
James T. Kessler - Anaheim CA
Assignee:
Beckman Instruments, Inc. - Fullerton CA
International Classification:
G01N 3320
US Classification:
436 74
Abstract:
Diluents and methodologies for determining the concentration of total calcium in a clinical sample (e. g. whole blood, sera plasma urine cerebro spinal fluid) containing protein-bound calcium are disclosed. Methodologies include the steps of: (a) admixing the sample with a diluent, the diluent including effective amounts of a pH buffer and at least two agents capable of complexing free calcium in the sample, where the agent-calcium complex association constants ("log K" in base 10) each have a range from about 1. 5 to about 7. 0; and (b) contacting an aliquot of the diluted sample with a calcium-specific ion selective electrode. The response of the calcium-specific ion selective electrode is an indication of the concentration of total calcium in the sample.

Solid State Ion Selective Electrodes

US Patent:
20210213442, Jul 15, 2021
Filed:
Jan 8, 2021
Appl. No.:
17/144624
Inventors:
- Brea CA, US
Xihai MU - Eastvale CA, US
International Classification:
B01L 3/00
G01N 33/487
G01N 33/84
G01N 27/403
Abstract:
An ion selective electrode (“ISE”) assembly may be installed within a sample path of a biological testing system to measure ion concentration within sample fluid flowing through the sample path. A transducer membrane is placed within a housing and positioned to contact the sample path. A threaded portion is advanced into a socket of the housing and forces the membrane against a sealing portion of the sample path to prevent retention of sample fluid within the housing after testing. Sealing may be accomplished without adhesives or sealants and instead relies upon mechanical pressure of the threaded portion. Another implementation includes a reference measuring electrode and several ion measuring electrodes combined into a single housing. Another implementation includes a reference measuring electrode and several ion measuring electrodes combined into a cartridge that includes a sample well instead of a sample path.
