    摘要： A method for cleaning of a measuring element (1) passed over by a gas flow is arranged on a thin-walled membranous material (5). The measuring element (1) includes at least one heatable element (6, 7, 8; 10, 11), which is arranged on the membranous material, the membranous material being capable of vibrating. By means of a control apparatus (20) or a switching (22) associated with the measuring element, a periodic delivery of current (41, 42) in intervals takes place in this manner to at least one heatable element (6, 7, 8; 10, 11) of the measuring element (1) and thereby produces vibrations. Alternatively, vibrations of the membranous material (5) can be produced by special vibration exciters or by means of ultrasonic coupling.

    摘要： A miniaturized temperature-zone flow reactor, used for thermally controlled biochemical or molecular-biological processes, especially polymerase chain reaction (PCR) enables more efficient reactions by providing at least one closed flow path which is divided into three partial paths (A1 . . . An; B1 . . . Bn and BB1 . . . BBn−1; C1 . . . Cn) with the reactor having three substrate chips (A; B; C) which are made of a material having a high heat conductivity, and which have defined channel sections that are spaced apart relative to each other, and are connected by a connecting chip (V) made of a poor heat-conductive material. The substrate chips (A; B; C) are maintained at different temperatures by various means, including the use of controlling heating elements in contact with the chips.

    摘要： The present invention relates to novel thin layers for microsystem techniques and microstructuring. It is an object of the invention to provide thin layers which can be manufactured under less problems and more economically than the previous conventional layers, and which permit the use of existing technologies for microstructuring. The object is realized in that the thin layer is formed of an enzymatically degradable biopolymer in a range of layer thicknesses of from 30 nm to 3 &mgr;m. Biopolymeric thin layers manufactured according to the invention permit their application, after a respective structurizing, as test assays or in setting up substance libraries.

    摘要： In a photo-thermal sensor for determining the concentration of a compound in a sample which includes an excitation light source generating a first light beam of a wave length which is well absorbed by the compound to be determined, a modulator and an optical lens system disposed in the first light beam such that the first light beam is constricted at the location of the sample through which it is directed, a probe light source generating a second light beam extending at a right angle to the first light beam, a beam divider arranged at the intersection of the first and second light beams whereby part of the first light beam is deflected at one side of the beam divider and the second light beam passes through the beam divider such that both beams incide on the sample anti a photo-sensitive detector arranged in the light beam path behind the sample, a diaphragm is arranged in the beam path directly after the sample and an expansion lens adapted to expand the second light beam at the location of the sample to a diameter at least 5 times the diameter of the first light beam is disposed in the path of the second beam ahead of the beam divider for determining the loss of strength of the second light beam reaching the detector after passage through the sample and the diaphragm as an indication of the concentration of the compound in the sample.
