Abstract  

Trace amounts of cadmium were determined by sub- and super-equivalence isotope dilution analysis in model solutions and water samples. Cd/II/ was labelled with109Cd and was extracted in CHCl3 as dithiozonate. AAS was chosen as reference analysis.

Abstract  

Trace amounts of progesterone were determined by sub- and super-equivalence isotope dilution analysis in model solutions and cow's milk. The samples were labelled with 11--hemi-succinate-/125I/-iodotyrosine methylesther progesterone and the separation of antibody-bound from free hormone was performed by adsorption on carbosorb. RIA-test-PROG M kit /SSR/ was used for reference analysis. The method is suitable for pregnancy testing.
