    Description / Table of Contents: Summary A description is given of the separation by means of thin layer chromatography of lower hydroxy-oxo compounds, which occur as degradation products of carbohydrates, from sugar acids and their lactones as well as sugar osazones. A new arrangement is given for improving the elution technique, and it also makes possible an increased sensitivity in the identification.
    Abstract: Résumé On décrit les séparations par chromatographie en couche mince des composés hydroxyoxo inférieurs apparaissant comme produits de dégradation des hydrates de carbone, des acides sacchariniques et de leurs lactones ainsi que des osazones provenant d'un sucre. Pour améliorer la technique de l'élution, on indique un nouveau déroulement de la technique opératoire qui permet en même temps d'augmenter la sensibilité au cours de l'identification.
    Notes: Zusammenfassung Trennungen von niederen Hydroxy-Oxoverbindungen, die als Abbauprodukte von Kohlehydraten auftreten, von Zuckersäuren und ihren Lactonen sowie Zuckerosazonen mit Hilfe der Dünnschichtchromatographie werden beschrieben. Zur Verbesserung der Elutionstechnik wird eine neue Anordnung angegeben, die auch eine Steigerung der Empfindlichkeit bei der Identifizierung ermöglicht.

    Description / Table of Contents: Summary A simple method for determining the total sulfur in organic material is described. This method is especially suited to quantities of sulfur from 10μg and upwards. It is based on the precipitation of sulfate by means of139Ba, whose gamma radiation can be readily measured.
    Abstract: Résumé On décrit un dosage simple du soufre dans les substances organiques. Cette méthode convient particulièrement pour les teneurs en soufre supérieures à 10μg. Elle repose sur la précipitation du sulfate par le139Ba, dont on peut facilement mesurer le rayonnement gamma.
    Notes: Zusammenfassung Eine einfache Bestimmung des Gesamtschwefels in organischem Material wurde beschrieben. Diese Methode eignet sich besonders für Schwefelmengen von 10μg aufwärts. Sie beruht auf der Fällung von Sulfat durch139Ba, dessenγ-Strahlung leicht gemessen werden kann.

    Description / Table of Contents: Summary An improved possibility of separating hexoses on silica gel and also on layers consisting of kieselguhr and 0.1M sodium acetate by means of a flow-through procedure is described and then a method is given for the quantitative determination of aldoses. The benzidine method described byPridham andJones has been modified for this purpose.
    Abstract: Résumé On indique la possibilité de mieux séparer les hexoses sur gel de silice et sur couches de kieselguhr par un procédé d'élution á l'acétate de sodium 0,1M puis l'on décrit une méthode pour évaluer les aldoses quantitativement. On a modifié dans ce but la méthode á la benzidine décrite parPridham etJones.
    Notes: Zusammenfassung Es wird über eine verbesserte Trennmöglichkeit der Hexosen auf Kieselgel wie auch auf Schichten aus Kieselgur und 0,1-m Natriumacetat mittels eines Durchlaufverfahrens berichtet und anschließend eine Methode angegeben, um Aldosen quantitativ zu bestimmen. Zu diesem Zwecke wurde die vonPridham undJones beschriebene Benzidinmethode modifiziert.

    Description / Table of Contents: Summary A combination of thin layer chromatography and the ring furnace technique is described. The possibility of identifying slight amounts of materials is thus improved.
    Abstract: Résumé On décrit une combinaison de la Chromatographie en couche mince avec la technique du four annulaire. On améliore ainsi la possibilité d'identifier de faibles quantités de substances.
    Notes: Zusammenfassung Eine Kombination der Dünnschichtchromatographie mit der Ringofentechnik wird beschrieben. Die Möglichkeit, geringe Substanzmengen zu identifizieren, wird dadurch verbessert.

    Description / Table of Contents: Summary A hydrochloric alcoholic solution of 2-methylindole is a sensitive reagent for malondialdehyde. A red dyestuff is formed with an absorption maximum at 555 nm. Since a linear proportionality prevails between extinction and concentration of the solution, this reaction may be employed for the photometric determination.
    Notes: Zusammenfassung Eine salzsaure alkoholische Lösung von 2-Methylindol ist ein empfindliches Reagens auf Malondialdehyd. Es bildet sich dabei ein roter Farbstoff mit einem Absorptionsmaximum bei 555 nm. Da lineare Proportionalität zwischen Extinktion und Konzentration der Lösung herrscht, kann diese Reaktion zur photometrischen Bestimmung verwendet werden.
