Abstract The cation exchange separation of metallic chlorides by hydrochloric acid on an Amberlite CG-120 resin (200-400 mesh) column was investigated. Commercially available resin was used in the experiments after the “fines” were removed by several water washings. A resin column (24 cm long by 12 mm diameter) gave excellent separation of sodium and potassium, with a total volume of 500 ml of 0.5N HCI at a flow rate of 0.55 ml/min. The recovery of each metal was 100%. Elution of the other three metals required 1100 ml of liV HCl; separation was very good but recoveries were poor. AH of the metals were determined with a Beckman DU with photomultiplier and hydrogen-oxygen flame attachment.

Abstract Separated erythrocytes are washed repeatedly with iso-osmolar magnesium chloride solution, lysed by adding saponin, and sodium potassium measured in the diluted hemolysate by flame photometry. The coefficient of variation for the method was less than 4%. Reference intervals determined for a healthy population and hospitalized (elective surgery) patients without electrolyte disorders were 4.6-7.8 mmol/liter for erythrocyte sodium concentration and 94-110 mmol/liter for erythrocyte potassium concentration (2.5-97.5 percentiles).
