    Abstract: Résumé En utilisant la technique classique du capillaire d'Emich, on a imaginé une méthode de détection simple des éléments que l'on rencontre le plus fréquemment dans les composés organiques.
    Notes: Summary UsingEmich's classical capillary technique, a simple scheme has been devised for the detection of the elements most frequently occurring in organic compounds.

    Description / Table of Contents: Zusammenfassung 0,1 bis 0,25 g der Substanz werden auf der analytischen Waage auf ein Zehntelmilligramm genau abgewogen und dann in einem Meßkolben von entweder 10,00 oder 25,00 ml Inhalt eingetragen und gelöst. Nach Auffüllen bis zur Marke werden 0,500 ml der Lösung mit einer Auswaschpipette zur Ausführung der Mikro-Kjeldahlbestimmung abgemessen. Methylalkohol und Äthylalkohol haben sich als Lösungsmittel bewährt.
    Abstract: Résumé 0,1 ou 0,25 g de substance sont pesés à 0,1 de mg près sur une balance analytique et portés respectivement dans un matras de 10,00 ou de 25,00 ml. Après dissolution et mise au trait, 0,500 ml sont prélevés à l'aide d'une auswaschpipette pour l'exécution d'un micro-Kjeldahl. L'alcool méthylique et éthylique se sont révélés de bons solvants.
    Notes: Summary Using an analytical balance, one weighs 0,1 g or 0,25 g of the substance to the nearest tenth of a milligram. The substance is then dissolved to give 10,00 ml of solution, of which 0,500 ml are used for the micro determination. Methanol and ethanol are recommended for solvents.

    Description / Table of Contents: Zusammenfassung Die Anwendung der Reaktion vonMendius auf das vonSozzi undNiederl modifizierte Lassaignesche Schmelzverfahren erlaubt den qualitativen Nachweis von Kohlenstoff und Stickstoff in Form von Methylamin, das auf verschiedene Weise identifiziert werden kann. Die Anwendung der Emichschen Kapillartechnik ergibt einen einfachen mikrochemischen Nachweis für diese beiden Elemente.
    Abstract: Résumé L'adjonction de la réaction deMendius à la méthode de fusion deLassaigne modifiée parSozzi etNiederl permet de déceler le carbone et l'azote sous forme de méthylamine que l'on peut identifier de diverses faCons à l'aide d'essais classiques bien connus. L'emploi de la technique du capillaire d'Emich permet de transformer la méthode décrite en méthode microchimique simple.
    Notes: Summary Augmenting theLassaigne fusion method, as modified bySozzi andNiederl, by theMendius reaction, allows the detection of carbon and of nitrogen as methyl amine which may be identified in several ways by well known standard tests. Employment ofEmich's capillary technique converts the above procedure into a simple microchemical method.

    Molecular weight determination by isothermic microdistillation (1949)
    Springer
    Microchimica acta 34 (1949), S. 132-141 
    Details
    ISSN: 1436-5073

    Description / Table of Contents: Zusammenfassung Die seinerzeit beschriebene Modifikation der Methode vonBarger mit Hilfe von „parallelen Zwillingskapillaren“ zur Bestimmung des Molekulargewichtes durch isotherme Mikrodestillation ist durch die vorstehend wiedergegebene Methode mit Hilfe von „gegenübergestellten Zwillingskapillaren“ dargestellt. Durch Verringern der Länge des Dampfraumes auf ein Minimum von 6 bis 8 mm und Verwendung von geeigneten Lösungsmitteln wurden deutliche, 10- bis 20fach größere Änderungen als bisher in 24 Stunden und endgültige Ergebnisse innerhalb 48 Stunden erhalten. Das Verfahren erfordert für einen Versuch nur 25 mm3 Lösung von 0,5 mg Substanz, die wiedergewonnen werden kann. Der Aufwand an Hilfsmitteln besteht aus drei Kapillaren und ist von äußerster Einfachheit.
    Notes: Summary The previously described “parallel twin capillary” modification ofBarger's method for the determination of molecular weight by isothermic microdistillation, has been superceded by the “opposed twin capillary” method described above. By reducing the actual length of the vapor bridge to a practical minimum of from 6 to 8 mm., and employing suitable solvents, significant readings, ten to twenty times as large as heretofore possible, are obtained in 24 hours and final results within 48 hours. The method requires only 25 cbmm. of solution per trial, involving as little as 0,5 mg. of substance which can be recovered. The apparatus consisting of three capillaries is of utmost simplicity.
