Oszillographische Verfolgung der polarographischen Brdička-Filtratreaktion

Polarographic Analysis of Proteins, Amino Acids, and Other Compounds by Means of the Brdička Reaction

“…The application of cathode-rby oscillographs for the rapid plotting of current-voltage curves on the screen of the cathode-ray tube has also been successful (57). While this is worthwhile for the rapid scanning of many samples, one still needs to photograph the picture for a permanent record.…”

Organic Polarography

“…The Brdicka test has been followed by both the classical and oscillopolarographic methods (283), and gives catalytic waves for sulfur compounds only if these form complexes ~i t h cobalt (593). The catalytic wave is higher for erythro-phenylcysteine than for the threo isomer (698), increases in size as the number of sulfur atoms increases in the hydantoin and pyrimidine series (706), and is given by allyl thiocyanate and mustard oil but not by sinigrin (202).…”
