The invention describes a detection system () for analytical separation processes, particularly for electrophoresis, characterized by an optoelectronic sensor layer () made from organic semiconductor materials extending along the carrier layer () for the sample to be tested, for detecting the separated sample.

System for detecting electrophoresis

The invention relates to a method of filling nozzles () of a dispensing system () of a test system () comprising a dispensing system () and a microfluidic device () comprising at least the following steps: (a) transporting the solution from the container () via the nozzle () of the dispensing system () to the sample application opening () of the microfluidic device () by means of a micro-pump (), (b) further transporting the solution into the measuring region of the microfluidic passage () of the microfluidic device (), (c) measuring a light signal in the measuring region of the microfluidic device () by means of at least one photosensitive sensor () with a plurality of photodetectors (), and (d) deactivating the micro-pump () when the light signal and/or a change in the light signal is detected.

The invention relates to a modular absorption measuring system () for fluid media comprising a detection module () and a sample module (), which comprises a sample chamber (). The detection module () comprises a detection system (), which also comprises an electromagnetic radiation source () and a quantum detector (). The radiation source () is designed for supplying light in the direction of the sample chamber () and the quantum detector () is designed for receiving light from the sample chamber (). The electromagnetic radiation source () is designed as an electroluminescence component and the detection module () and the sample module () are also designed to be arranged on top of one another.

Modular absorption measuring system

The invention relates to a measuring arrangement for optically evaluating a chemical reaction quantitatively, comprising a sample carrier having a carrier layer and a sample layer having an analysis side and a light outlet side opposite the analysis side, and comprising a photosensitive sensor having a plurality of photodetectors on a carrying body and having a transparent surface layer arranged over the photodetectors. A plurality of test sections are arranged on the analysis side at a distance from each other in a longitudinal direction of the sample layer. The analysis side is arranged on the carrier layer in such a way that the test sections face a volume of a microfluidic system. The sample carrier is detachably arranged in an accommodating device, so that the light outlet side faces the photosensitive sensor and the test sections are arranged over the photodetectors. Furthermore, the distance between the test sections and the photodetectors is less than 700 &#x3bc;m.

Measuring arrangement for optically evaluating a chemical reaction quantitatively

The invention relates to a sample device () comprising an array of reaction chambers/wells () in a titer plate () and a two-dimensional array () of thin-film-light sensor elements (), and each light-sensitive element () of the sensor array () is disposed directly underneath the individual reaction chamber () in order to detect chemical and/or biological reactions.

Titer plate with thin-film-light sensor

Device () for optoelectronically characterizing samples by means of electrochemiluminescence (ECL), in which an electric voltage applied across a counter electrode () and a working electrode () on which the sample spots are disposed excites the sample to luminescence and a reading of the luminescence is taken using an optoelectronic component, characterized in that the optoelectronic component comprises an image detection component () with a photoactive layer () made from organic semiconductors between two electrode layers ().

Device for optoelectronically characterizing samples

The underlying objective is to create an optoelectronic sensor system which illuminates the specimen homogenously and only allows produced fluorescent light to reach the photoactive layer. The objective is achieved substantially by creating a total reflection layer for the introduced light before or above the optoelectronic sensor layer. This can be applied in all fields in which microarray biochips are used.
