Abstract A convenient screening procedure for presence of drugs of abuse in urine consists of two steps: adsorption of the drugs from urine onto a paper loaded with cation-exchange resin and detection of the adsorbed drugs by direct radioimmunoassay. The first step can be performed in the field, the second in a central laboratory. Storage and transport to the laboratory are simplified because specimens adsorbed on dried paper are stable and can be sent in letter-mail. In the laboratory, a small disc of the ion-exchange paper is exposed to antigen and antibody, rinsed, and tested for radioactivity. Discs treated with positive urines are more radioactive than discs from negative urines.

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.

Abstract The study of the separation of metallic chlorides on Amberlite CG-120 (200–400 mesh) cation exchange resin was continvied. Na, K, Mo, Al, Ca, and Fe have been separated by hydrochloric acid solutions and determined by polarography or flame photometry. Semimicro quantities of these metals can be separated from each other with a minimum of eluting agent, small resin beds, and simple equipment. Mechanical grading of the air-dried resin was used to obtain more uniform particles. The ion exchange separation scheme offers advantages over present official procedures, and it should provide a unified method for the analysis of metals in mixtures. Further study is recommended.
