Abstract: The present invention relates to a method for determining the condition of a biological fluid by recording the IR spectrum of a sample of the biological fluid. To this end, the biological fluid can be examined in its native form. The method of the invention is usable, for example, for detecting pathological conditions in organisms.

Abstract: The invention relates to a process for producing a flow cell for the spectroscopic analysis of samples to be passed through, the process comprising the following steps: (a) provision of a first (10) and of a second (22) window, the second window (22) having at least two sample flow channels (24) for supplying and removing the sample to be analyzed; (b) application of a structured thin layer (18) to one of the windows (10, 22); (c) contacting and liquid-tight securing of the thin layer (18) to the other (22, 10) window, in such a way that facing, plane-parallel window surfaces (14, 20) of the windows (10, 22) and the thin layer (18) delimit a flow chamber (26) which is accessible only through the sample flow channels (24), the windows (10, 22) being optically transparent at least in some regions at least in the region of the flow chamber (26); and (d) filling at least some regions of a filling chamber (28) between the windows (10, 22) which is separated from the flow chamber (26) by the thin layer (18) and ad

Abstract: The invention relates to a method and a device for identifying active substances in order to determine the formation of complexes between reactants. According to the inventive method, at least two reactants are mixed and made to react to form a complex. The infrared spectrum of the individual reactants which have not yet been reacted in the mixture is measured during a first time interval and at least a second infrared measurement is conducted to measure the complex formed by the reactants during a second interval. The difference between the two spectra measured during different moments is then determined. The reactants whose differential spectrum exhibits a band structure are selected as active substances.
