Abstract:
The invention relates to an arrangement for continuous determination of a substance comprising a chemically reacting sensor element (21) arranged in or adjacent to a limiting wall of a volume (22) containing the substance, where in a housing (2) of a modular device (1) optical elements to read the sensor element (21) are arranged, comprising at least one light source (35) illuminating the sensor element (21) and at least one sample detector (29) detecting the light scattered by the sensor element (21), and where a front side of the housing (2) comprises a coupling for the sensor element (21), so that the sensor element (21) may be interchangeably and modularly coupled to the front side of the housing (2). A glass body (24) is arranged adjacent to the coupling for direct contact with the sensor element (21) and separate conduits (34, 31) for the illuminating and for the scattered light are arranged rearward of the glass body (24). The modular device (1) allows for easily interchanging the modular sensor element (21) and provides an optical connection between the sensor element (21) and the detector (29) which is steady and allows for high quality measurements.
Abstract:
A dermatologically effective topical composition, particularly for the prevention and treatment of skin diseases, comprises a textile carrier made of cellulose-containing fibers, which are provided with an acidically acting surface layer. The wash-resistant acid coating can be produced by esterification using a polycarboxylic acid, particularly citric acid, and after up to 20 wash cycles using a detergent having a neutral pH has a pH value of no more than 6.5 measured on the surface of the coating.
Abstract:
Eine dermatologisch wirksame topische Zusammensetzung, insbesondere zur Prävention und Behandlung von Hautkrankheiten umfasst einen textilen Träger aus cellulosehaltigen Fasern, die mit einer sauer wirkenden Oberflächenschicht versehen sind. Die waschbeständige saure Beschichtung ist durch Veresterung mit einer Polycarbonsäure, insbesondere Zitronensäure, herstellbar und weist nach bis zu 20 Waschgängen mit einem pH-neutralen Waschmittel einen an ihrer Oberfläche gemessenen pH-Wert von höchstens 6.5 auf.
