MESSANORDNUNG MIT EINEM FÜR ANREGUNGS- UND MESSSTRAHLUNG TRANSPARENTEM TRÄGERELEMENT

摘要

The carrier medium (1) has luminescence sensors (2) on one surface (11). The incident illumination enters from a source (3) via the lower surface (12) and the luminescent radiation reaches the detector (4) at right angles to the incident beam direction via a surface (13). A common capillary channel (6) in a housing (7) for the sample links the sensors. The carrier medium is divided into separate detector channels in a comb structure by dividers (8) or optically impervious layers. The detectors are connected to an analyser (5) via electro-optical switches. Separate sources may be used to generate a pulsed sequence or modulation of the exciting radiation; the decay time of the detector signal is analysed.
