Abstract: The invention relates to a filter element for filtering fluids, comprising at least one filter unit (12, 14,16) that is disposed concentrically around the axis of said element, said unit being supported on at least one supporting element (24, 26, 30) in the direction of flow of the fluid. According to the invention, at least part of the supporting elements (24, 26) is provided at least on the side facing the filter unit (12, 14, 16) with channels (28) for guiding the fluid. Longitudinal ribs (50), which delimit said channels (28), extend along the supporting element (24, 26) in the form of spiral tracks. The two free ends of each channel (28) emerge at opposite ends of the corresponding supporting element (24, 26). The channels (28) extend continuously along the supporting element, are devoid of multiple deviations in the fluid flow and only partially surround the corresponding supporting element (24, 28), thus forming a torsional, guide for the fluid flow.

Abstract: A process and apparatus for testing material libraries, in particular catalysts, by means of coupled use of at least two analytical methods, preferably IR thermography and mass spectrometry. Owing to the selected arrangement, the disadvantages of the two previously known individual methods are compensated for: the subsequent selectivity determination for selected sections by means of mass spectrometry invalidates the argument against IR thermography, of only being able to determine activities; the rapid integrated determination of potentially “good” materials via IR thermography prevents an excessive loss of time by needing to test all materials of a library successively with the mass spectrometer.
