Abstract: In summary, the present invention relates to a method for analyzing and/or testing at least one user interface, comprising the steps of: transmitting an address of at least one user interface, in particular a web-based user interface, and/or a source code together with the associated graphical elements of at least one user interface, in particular a web-based user interface, to an evaluation apparatus (10); transmitting the address of the at least one user interface and/or the source code together with the associated graphical elements of the at least one user interface to at least two differently configured presentation apparatuses (12, 14); generating at least one pixel image of the user interface on each presentation apparatus (12, 14); transmitting each generated pixel image to the evaluation apparatus (10); automatically determining and/or representing at least one difference between the generated pixel images of the at least one user interface.

Abstract: The present invention relates to a fixed bed, for example for the isolation and/or purification of components originating from a biological system, which fixed bed comprises magnetic beads and a magnetizable fabric arranged at least in part in the fixed bed, a fluidized bed-fixed bed, which comprises the fixed bed of the invention after application of an alternating magnetic field, and also to a process for the isolation and/or purification of components originating from a biological system.

Abstract: The invention relates to a method of determining material properties of a contact formed between a measurement tip of a microscopic probe and a sample surface of a sample material. According to the method, a distance modulation is applied for modulating a distance between a support of the microscopic probe end the sample surface in a direction essentially normal to the sample surface and wherein a normal force signal indicative of a normal force is measured and demodulated. In the method it is proposed that the material properties be determined using measurement data comprised in the demodulated normal force signal and related to a (concave) buckling deformation of the microscopic probe relative to and away from the sample surface.
