    摘要: The invention relates to a method for determining the swelling behavior and the swelling kinetics of super absorbent materials (9) such as polymer gels, whereby a defined volume of dry super absorbent materials (9) is introduced into a measuring vessel (7), and a pressure force (12) is exerted onto the super absorbent material (9) by means of an element (4) that can be displaced inside the measuring vessel (7). The expansion of the super absorbent material (9) inside the chamber (14) is continuously detected by means of a non-contact detection of the change in height of a tube (4), which delimits the chamber (14), is guided inside a measuring vessel (7), and which is provided with a height marking (6).

    摘要: The invention relates to a method and a device for the parallel, automated analysis of blushing in n samples of dispersion films. According to said method: (a) an illuminated array of n spatially separate samples of dispersion films is prepared, (b) the array of n samples is photographed using a CCD camera at m+l different points in time to to tm and the photographs are digitised, (c) from said m+l different digitised photographs for at least part of the n samples, several luminosity values B (k, ti) are determined automatically for each sample at different points in time ti, selected from to to tm, whereby B (k, ti) is the luminosity value of the k-th n sample at each point in time t; and represents a measurement of the blushing in said sample at said point in time, (d) from said different luminosity values B (k, ti) for at least part of the n samples, values P (k) for a parameter that characterises the kinetics of the blushing is determined for each sample, whereby P (k) is the value of the characteristic parameter for the k-th n sample.
