Abstract: The present invention relates to a gas detector cell unit comprising a gas cell, the unit comprising an outer housing providing access to the gas outside through a protecting filter adapted to making gas cell safe for use in explosive environments, i.e. a sintered filter, and the unit comprising means for detecting reduction in the circulation through said protecting filter.

Abstract: A method for fabrication of a lab-on-a-chip system makes use of first and second mold parts, which are adapted to join each other to form a cavity to accommodate a positioning means and a support structure. The method includes receiving the chip in the positioning means, forming the cavity by joining the first and second mold parts, securing the chip with a fluid port of the chip to rest on the support structure for the support structure to mask the fluid port, introducing a molding material into the cavity to over-mold at least part of the chip and a volume extending away from the chip, separating the first and second mold parts, and extracting the chip from the mold. A fluid channel is formed by the support structure.

Abstract: This invention relates to a system and method for detecting target molecules using an optical sensor element including a photonic crystal constituted by a membrane of a chosen transparent material, being provided with a number of defined openings in a chosen pattern, a chosen number of the openings providing capture molecules having a high affinity to target molecules, the pattern being adapted to provide resonance at a chosen wavelength, or range of wavelengths. The system and method also moving a first fluid flow containing target molecules through the openings and after this conducting a second fluid flow containing a second reactant being different from the capture molecules but having a high affinity for the target molecules but a low affinity for other possible molecules in the first flow. By illuminating the sensor element at a chosen wavelength thus obtaining a resonance and imaging means for providing an image of the sensor element it is possible to detect tight leaking from the resonator.
