In the present work, we assessed the suitability of sodium and potassium physiologically present in sweat, as internal reference allowing to re-calculate the corresponding volume of sweat collected on a PharmChek Patch. A method using capillary electrophoresis with indirect ultra-violet detection was developed for the determination of sodium and potassium in sweat. The concentrations determined in specimens collected from 12 females and 10 males, using a home-made system composed of… CONTINUE READING
