    摘要: The sensor membrane of an optical sensor for detection of O.sub.2, H.sub.2 O.sub.2, SO.sub.2 or halogenated hydrocarbons in a sample contains an indicator substance that is homogeneously immobilized in the polymer matrix of the sensor membrane and is, at least indirectly, in contact with the sample, changing at least one of its optical properties upon a change of the parameter to be measured. The indicator substance contains an inorganic salt of a transition metal complex with .alpha.-diimine ligands. The indicator substance is homogeneously distributed in the polymer matrix, which essentially consists of at least one substance belonging to the group of cellulose derivatives, polystyrenes, polytetrahydrofuranes, or their respective derivatives.

    摘要: For quality control of packaged organic substances, preferably packaged foods and drugs, the materials to be examined are brought into contact with a planar optical sensor element which is applied on the inside of the wrapping and responds to a change in the gas composition in the gas space above the sample by a change in color or fluorescence. The change of one of the optical properties of the sensor element is detected visually or opto-electronically.

    摘要: In order to improve a one-way measuring element, which may be inserted into an analyzer for analyzing gaseous or liquid samples and which comprises a measuring channel with a measuring zone and one or more sensors located therein, the proposal is put forward that the one-way measuring element be provided with a sensor part whose measuring channel has seals on both ends, and with a sample-taking part, and that a coupling element be placed at the inlet end of the measuring channel for direct coupling of the sample-taking part containing the gaseous or liquid sample, and that the measuring channel be filled with a calibrating and storage medium prior to the measuring process, and that the calibrating and storage medium contained in the measuring channel be displaced by the sample flowing in after the sample-taking part has been coupled to the sensor part. The one-way measuring elements obtained in this way are characterized by great simplicity of design and ease of handling.

    摘要: One measurement each is obtained from two optical sensors of ion concentration, following which the measured values are used for empirical determination of the ionic strength of an electrolytic solution. The sensors contain the same indicator substance but differ with regard to surface modification, thus ensuring different responses to ionic strength in spite of identical excitation and fluorescence wavelengths and the resulting simplicity of the optical system.

    摘要: For the purpose of reversible optical indication of the pH of a sample, a hydrophilic accommodating layer is disposed on a hydrophobic mechanically stable support element, which layer contains the indicator dye proper in an immobilized form. This provides a sensor membrane which can be fabricated in a simple manner and is cost-effective, which has a rapid response time and can also be fabricated as a mass product to be used only once.

    摘要: An optical method for quantitative determination of human serum albumin (HSA) in biological liquids such as urine is based on the observation that the absorption and fluorescence of certain anionic cyanine dyes possessing a terminal cyano group and having the general formula ##STR1## are strongly affected by HSA. This approach is distinctly more sensitive than existing techniques, allowing the detection and quantization of micro-albuminuria (i.e. detection of HSA in the 1-10 mg per liter concentration range) at costs which are distinctly lower than those for existing immunological assays. It is also much more specific for HSA than existing assays based on dye binding. Because the dyes has long wave absorptions and emissions, use can be made of electro-optical components based on semiconductor technology.
