An analysis element for the determination of an analyte in a liquid sample, especially for medicinal uses. A carrier layer (2) contains, in a reagent domain (4), a reagent applied in a defined pattern by an ink-jet process. The pattern comprises several sets (A, B, C) of compartments (11-20), the compartments (e.g. 11, 13, 15, 17, 19) of the same set (e.g. A) having the same chemical composition, the compartments (11, 13, 15, 17, 19 or 12, 16, 20) of different sets (A or B) containing different reagents and the compartments of different sets being arranged in alteration so that the compartments containing different reagents are close together but nevertheless spatially separated.

Analysis element and process for its manufacture

A method for the metered application of a biochemical analytical liquid to a target, wherein the liquid is ejected in small quantities on to the target through a jet from a jet chamber by a procedure in which a partial volume of the liquid in the jet chamber is evaporated and expanded for a short time whenever a quantity of the liquid is to be ejected. The invention further relates to a device with a disposable jet element which contains prepackaged analytical liquid.
