    Notes: Summary The new phase ratio variation method is described which represents a convenient way for the determination of gas-liquid partition coefficients for practical purposes, utilizing equilibrium headspace-gas chromatography (EHS-GC). This method is based on the relationship between reciprocal peak area and the phase ratio in the vial containing the sample solution; it involves regression analysis of the EHS-GC measurements of a number of sample vials containing the same sample solution but with a wide variation of phase ratios. Examples are given for both aqueous systems and systems consisting of a stationary (liquid) phase used as the solvent; comparison of the measured values with results obtained by other methods shows satisfactory agreement. A critical discussion of the conditions influencing the accuracy of the analytical results is given.

    Description / Table of Contents: Zusammenfassung Mit der automatischen Abtastung und Speicherung von Volumina bietet die 3D-Technik heute die Möglichkeit, Strukturen in einzelnen Schritten tomographisch genau zu analysieren. Aus dem elektronischen Speicher können Bildebenen, die mit konventioneller Technik nicht darstellbar sind, ohne Probleme rekonstruiert werden. Oberflächen- und Transparenzmode erlauben zusätzlich eine plastische Darstellung von gespeicherten Strukturen. Mit diesen unterschiedlichen Darstellungsmöglichkeiten und der verlustfreien Langzeitspeicherung von Volumina setzt die transvaginale 3D-Sonographie neue Maßstäbe in der Feindiagnostik der Frühgravidität.
    Notes: Summary Three-dimensional imaging with the capacity for automatic data acquisition and volume storage provides the possibility of analyzing structures tomographically in certain steps. Sectional planes that cannot be demonstrated by conventional ultrasound can be calculated and displayed from the volume memory. In addition, three-dimensional images may be calculated using the surface and transparent mode. With those different viewing modes and permanent storage of the acquired volumes, the transvaginal 3-D technique offers a precise diagnosis in early pregnancy.
