    摘要: Fluoroionophores that are functionalised with reactive groups and correspond to the formula I—R1—F—R2—G, wherein I is a monovalen residue of an ionophore, wherein F is a divalent residue of a fluorophore, wherein G is a functional group and R1 and R2 are each independently of the other a direct bond or a bridging group. The fluoroionophores may be covalently bound to carrier materials and are used as active components in polymer membranes of optical sensors for the detection of ions. The sensors are distinguished by a long usable life and a high degree of sensitivity.

    摘要: In the optical detection device (1), the excitation light guide (11) and the emission light guide (12) form a structural unit having the end face (14) facing the fluorescence changer (4). The end face (14) physically corresponds substantially to one of the boundary surfaces of the two light guides (11, 12). As a result, the detection device (1) can be separated in a simple manner into an optical part and a mechanical part which are in optical contact only by way of the end face (14). All of the elements in the optical light path are connected in a mechanically stable manner by means of the index-matching medium 20, as a result of which the light between the light source (10) and the photoelectric sensor (13) propagates only in media having a comparable refractive index. The light source (10) is preferably a light-emitting diode. A plurality of those detection devices can be combined to form a compact detection apparatus with which the substance (3) can be examined with regard to several constituents in one measuring operation.
