Patent number: 11630094Abstract: Described is an oxygen permeable layer for detection of molecular oxygen, wherein the layer has a carrier material in which at least one particle is comprised, wherein the carrier material is polyvinylidene fluoride or a copolymer of polyvinylidene fluoride, and the particle comprises a polymer or a copolymer, wherein the polymer or copolymer of the particle has a chemically covalently bonded indicator compound for detection of molecular oxygen. In addition, a multilayer system for detection of molecular oxygen is described. Also described are a method for producing the layer, and the use of the layer or of the multilayer system for detection of molecular oxygen.Type: GrantFiled: October 13, 2017Date of Patent: April 18, 2023Assignee: Hamilton Bonaduz AGInventors: Claudius-Michael Ortega Schulte, Dirk Schönfuss, {hacek over (S)}pela Willi, Sara Simonato

Publication number: 20210302352Abstract: A pH combination electrode includes inner and outer tubes, working and reference electrodes, and a hydrogel diaphragm between the tubes. A seal is disposed inside the inner tube closer to a first inner tube end than to the second inner tube end. An extended reference chamber is formed inside the inner tube between the seal and the second inner tube end. A first conductive fluid is contained in the inner tube between the seal and the first inner tube end. A second conductive fluid is contained in the extended reference chamber and in a reference chamber formed between the inner and outer tubes. A through-hole in the inner tube allows the second conductive fluid to flow between the reference chamber and the extended reference chamber. The working electrode extends into the inner tube, through the seal and into the first conductive fluid. The reference electrode contacts the second conductive fluid.Type: ApplicationFiled: June 11, 2021Publication date: September 30, 2021Inventors: Gabriela Fisch, Theo Gaupp, Dirk Schoenfuss, Claudius-Michael Ortega Schulte

Patent number: 10161871Abstract: The invention relates to a sensing unit (1) comprising a housing (2) that has a first housing opening which can be oriented towards a medium (M) to be analyzed, and a second housing opening on which at least one means for detachably rigidly connecting to a sensor shaft or sensor housing are arranged, or may be arranged, on the inner and/or outer side; at least one sensor element (3) that is arranged in the housing (2) and comprises indicators and, optionally, indicator protectors, said sensor element (3) having a first side facing the first housing opening and a second side lying opposite the first housing opening; and at least one protector element (4) which is arranged in the region of the first housing opening between the at least one sensor element (3) and the medium (M) which surrounds the sensing unit (1), particularly in the region of said housing opening, such that the sensor element (3) does not come into direct contact with the medium (M).Type: GrantFiled: November 27, 2013Date of Patent: December 25, 2018Assignee: HAMILTON BONADUZ AGInventors: Dirk Schoenfuss, Claudius-Michael Ortega Schulte

Patent number: 9952187Abstract: The invention relates to an optical sensor element, comprising indicators, selected from luminescence-active means that are of the same type or different, and indicator protectors, and to a sensor, comprising at least one such sensor element, an energy source that excites the luminescence emission of the indicators, and a detector unit, wherein the sensor element or sensor is suitable for detecting molecular oxygen in a gaseous or liquid medium and/or for determining the molecular oxygen content of a gaseous or liquid medium and at least one layer of the sensor element bearing the indicator protectors is designed in such a way that the diffusion rate of the molecular oxygen formed on the indicator protectors by means of the reduction of strong oxidants back into the medium is greater than the diffusion rate of molecular oxygen from the medium in the direction of the at-least-one layer bearing the indicator molecules.Type: GrantFiled: August 10, 2016Date of Patent: April 24, 2018Assignee: Hamilton Bonaduz AGInventors: Dirk Schoenfuss, Claudius-Michael Ortega Schulte
