USE OF POLYOXYALKYLENE NONIONIC SURFACTANTS WITH MAGNESIUM ION SELECTIVE ELECTRODES |
摘要 |
Methods are disclosed for reducing the shift in EMF bias in a magnesium ion selective electrode, comprising the step of: contacting the electrode with a composition comprising a polyoxyalkylene nonionic surfactant; wherein the polyoxyalkylene nonionic surfactant has an HLB greater than about 18. Additional aspects of the present invention are directed to methods, comprising the steps of: contacting a magnesium ion selective electrode with a composition comprising a polyoxyalkylene nonionic surfactant, wherein the polyoxyalkylene nonionic surfactant has an HLB greater than about 18; and measuring a biologically relevant level of a blood electrolyte in a blood composition with the electrode. In certain embodiments, the polyoxyalkylene nonionic surfactant is polyoxy ethylene (100) stearyl ether and the blood electrolyte is magnesium ion. |
