Simultaneous determination of the most abundant cationic species in human urine by capillary isotachophoresis.


Analytical isotachophoresis has proved to be an excellent method for separation and quantitative measurement of ionic species in biologic fluids. Isotachophoretic separation of cations in presence of a complex-forming nonionic detergent (e.g. Triton X-100) in 98% methanol enables simultaneous quantitative determination of ammonium, sodium, potassium… (More)
