The invention relates to a device for performing immunological, histochemical and cytochemical, molecular biological, enzymological, clinical-chemical and other analyzes, wherein the device comprises an object holder having one or more elongate adhesive surfaces and a reagent holder having one or several channels. The object holder is detachably connectable to the reagent holder in such a manner that the elongate adhesive surfaces each face one of the channels and, when reaction partners bound to a solid phase are disposed on the elongate adhesive surfaces and reactants dissolved in liquid are present in the channels, the reaction partners and the reactants are in contact. Means are provided for preventing the liquid from passing from one channel into an adjacent channel. A method for performing a corresponding analysis can be performed with this device, by connecting the object holder to the reagent holder in such a manner that the elongate adhesive surfaces each face a channel, liquid having reactants dissolved therein is introduced into the channels such that the solid phase substrates having reaction partners bound thereto and being disposed on the adhesive surfaces come into contact with the liquid, and the object holder and the reagent holder are moved together in such a manner that the liquid alternately moves into the two longitudinal directions of the channels.

The invention relates to an apparatus and a method for improved correction of drift in an infrared measuring instrument. The measurement signal furnished by a thermal detector is split into a direct voltage component and an alternating voltage component. By means of calibration curves (), a calculated comparison variable is formed from a measured, averaged concentration value The correction value &#x394;T for the drift correction is obtained from the difference between the corresponding measured size of the direct voltage component and the comparison variable
