Thirty-four edematous cardiac patients who were being treated with cation exchange resin were studied for its long term effectiveness and for clinical and chemical complications. In 23 of 27 patients the resin was effective in terms of mobilizing edema fluid previously refractory to other forms of treatment, of partial or complete substitution for mercurial diuretics, and of permitting a slight...
Ion-exclusion/cation-exchange chromatography (IEC/CEC) on a weakly acidic cation-exchange resin using on acidic eluent, developed by Tanaka et al. in 1994, has been employed to monitor the quality of environmental water samples such as acid rainwater and river water, to analyze body fluid samples such as saliva, and to evaluate water purification by photocatalytic materials.1–8 One advantage of...
This paper introduces a new off-line sample preparation that eliminates carbohydrates from amino acid samples containing a high carbohydrate content before analysis by anion-exchange chromatography and integrated pulsed amperometric detection. First, the sample is introduced into a cation-exchange column in the hydrogen form. Carbohydrates are removed completely using 0.02% formic acid as a tra...
