title: [Semi-automated determination of urinary 17-oxosteroids in a continuous flow system (author's transl)].
abstract: A semi-automated determination of 17-oxosteroids in urinary extracts is described using a modified Zimmerman reaction in aqueous phase according to Epstein. In order to eliminate the interfering chromogens a double manifold and a double-beam colorimeter are used in continuous flow. The spectra and the chromogenecity of seven different 17-oxosteroids are presented. The specificity and the reproducibility of this technique are good and the comparison with gas-liquid chromatography and manual Zimmerman reaction shows a good correlation.
