Open the CIPO recordAbstract From the Canadian patent
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 mol/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 …

Why it's free to use
- Filed March 21, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 21, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 21, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
