    Notes: [Auszug] THE letter by Klit and Langseth in NATURE of June 8 (p. 956), recording Raman frequencies of some deuterobenzenes, leads us to report our own results so far as these overlap, although we had wished to reserve publication until the problem of which these spectra supply only part of the answer ...

    A microscheme for cations without hydrogen sulphide (1951)

    Description / Table of Contents: Zusammenfassung Nach Fällung der unlöslichen Chloride und Behandlung mit Salpetersäure zur Entfernung von Zinn und Antimon kann für den Trennungsgang des Restes der „gewöhnlichen“ Kationen mit Natriumsulfat und Ammoniumhydroxyd als Fällungsmittel das Auslangen gefunden werden. Schwefelwasserstoff oder sonstige sulfidhaltige Reagenzien können so vermieden werden. Im Mikromaßstab konnten in diesen Trennungsgang neben den üblichen Kationen auch die Elemente Wolfram, Titan, Molybdän und Zirkon aufgenommen werden.
    Abstract: Résumé Après précipitation des chlorures insolubles et traitement par l'acide nitrique pour éliminer l'étain et l'antimoine, le reste des cations «communs» peut être séparé en employant schématiquement du sulfate de sodium et de l'ammoniaque seulement comme précipitants. Ceci évite l'emploi soit de l'hydrogène sulfuré soit d'un réactif à base d'ion sulfure. A l'échelle micro, ce mode de séparation a été étendu pour inclure le tungstene, le titane, le molybdène et le zirconium avec les cations plus usuels.
    Notes: Summary After precipitation of the insoluble chlorides and treatment with nitric acid to remove tin and antimony, the remainder of the “common” cations may be separated schematically using only sodium sulphate and ammonium hydroxide as precipitants. This avoids the use of either sulphuretted hydrogen or a potential sulphide ion reagent. On the micro scale this mode of separation has been extended to include with the more usual cations the elements tungsten, titanium, molybdenum and zirconium.

    Description / Table of Contents: Zusammenfassung Ein Mikromanipulator für die speziellen Bedürfnisse der chemischen Untersuchung von Gammamengen wird beschrieben. Das Instrument trägt eine Mikropipette, die mit Hilfe einer Mikrometer-Injektionsbürette kontrolliert wird. Diese Pipette wird mittels des Manipulators in die Reaktionsgefäße eingeführt, die auf dem drehbaren Tisch eines Mikroskopes mit schwacher Vergrößerung angebracht werden.
    Abstract: Résumé On décrit un micromanipulateur spécialement destiné à faire face aux besoins du travail chimique à l'échelle du microgramme. L'instrument porte une micropipette controlée par une seringue micrométrique et actionne celle-ci par rapport aux vases qui sont portés par la plateforme tournant mécaniquement d'un microscope de faible puissance.
    Notes: Summary A micromanipulator is described which has been specially designed to meet the requirements of chemical work on the microgram scale. The instrument carries a micropipette controlled by a micrometer syringe, and manipulates this in relation to the vessels, which are carried on the rotating mechanical stage of a low-power microscope.

    Description / Table of Contents: Zusammenfassung Für die Trennung und Identifizierung von Anionen [Cyanoferrat(II), Cyanoferrat(III), Cyanokobaltat, Wolframat, Molybdat, Jodat, Bromat, Chromat, Perjodat, Chlorat und Nitrit] unter Verwendung von 2 bis 5μl Lösung eignet sieh ein von den Autoren beschriebener, mit einem Schlitz versehener Ofen. Die Anionen werden in vier Gruppen aufgeteilt und dann identifiziert.
    Abstract: Résumé On a cherché à réaliser un four à baïonnette pour la séparation et l'identification d'anions (ferrocyanure, ferricyanure, cobalticyanure, tungstate, molybdate, iodate, bromate, chromate, periodate, chlorate et nitrite) sur 2–5μl de solution. On sépare les anions en quatre groupes sur lesquels on peut identifier les anions individuels.
    Notes: Summary A slotted oven has been devised for the separation and identification of anions (ferrocyanide, ferricyanide, cobalticyanide, tungstate, molybdate, iodate, bromate, chromate, periodate, chlorate and nitrite) using 2–5μl of solution. The anions are separated into four groups within which individual anions may be identified.
