Ion Exchange Method

Abstract An ion exchange method to determine the alkalinity of water-soluble tea ash containing high levels of manganese is described. A chromatographic column containing a strong cation exchange resin (20–50 mesh) in Na+ form, with a bed volume of 5 mL is used. The present ion exchange method is compared to pH titrations and also to the official AOAC methods (31.012, 31.015, 31.016). Results with the new method are accurate and precise.

Serum And Urine

Abstract The Jaffè reaction, used to determine creatinine in urine and plasma or serum, gives a positive error in the latter because of the interference of noncreatinine. In man (particularly children) endogenous creatinine normally occurs at a relatively low concentration in serum (0.3-1.0 mg./100 ml.). The analytic error contributed by noncreatinine chromogens, therefore, may be considerable. Of various manual methods to eliminate this none has been used with automated creatinine analyses, which generally measure total creatinine-like chromogen. In the present investigation a strong cation-exchange resin is used manually for rapidly adsorbing and desorbing "true" creatinine from plasma which is then analyzed by an automated method. A phosphate buffer (pH 12.4) is substituted for 5% (w/v) NaOH, dialysis eliminated, and the instrument manifold design is modified. Concentrations of "true" creatinine from 0.2-2.0 mg./100 ml. can be determined at a rate of 20 samples per hr. in serum or 40/hr. in urine, with a recovery of 98-101%.
