Method and device for obtaining and detecting immunologically active substances from the gas phase

Method of detecting surface contamination by an analyte

A protective element for an electrochemical accumulator is made of granular varistor material, the mean diameter of the grains of the varistor material being less than 1 .mu.m, in particular less than 250 nm and, for more than 60% of the grains of the varistor material, the grain size deviating by at most 40% from its statistical average. For the preparation of such grains, a dispersion is made up to form biochemical hollow bodies which have an internal diameter in accordance with the above requirements. The dispersion is admixed with salts which dissolve in the dispersion with the formation of intermediate ions of a substance forming an intermediate for a varistor material, the intermediate ion of a substance forming an intermediate for a varistor material being an intermediate ion of an element required for the varistor material or of a corresponding compound. The intermediate ions of a substance forming an intermediate for a varistor material are positioned in the enclosed void of the hollow bodies, being used to form the grains of the varistor material or an intermediate of corresponding shape, which are released by removing the sheath of the hollow bodies.

The invention relates to a charge exchange body with a large active surface as well as the method for its manufacture. The porous supporting structure of the charge exchange body is made of granular structural material, with the average diameter of the grains of the structural material being smaller than 1 .mu.m, especially smaller than 250 nm, and with the grain size differing by a maximum of 40% from its statistical average in more than 60% of the grains of the structural material. In order to make such grains, a dispersion is mixed with biochemical hollow bodies that have an inside diameter according to the above requirements. Salts are added to the dispersion and dissolve therein to form structural ions, with the structural ion being an ion of an element required for the structural material, or a corresponding compound. The structural ions are arranged in the closed cavity of the hollow body, with the grains of the structural material or a preproduct of corresponding shape being formed with them and released by removal of the shells of the hollow bodies.

Charge exchange body with large active surface and a method for

An adsorber material for collecting, concentrating and/or recovering gaseous and/or particle-shaped trace substances from an air or gas flow, in which the adsorber material is composed of fibrous elements made of natural and/or synthetic, organic, textile fibers which are worked into a nonwoven web having a planar geometry, the nonwoven web having a thickness of between 100 .mu.m and 2 mm and a weight per unit area of between 20 and 200 g/m.sup.2. Preferably the fibers have a fiber size between 1 and 10 dtex and are composed of cellulose and/or polyester, and if desired, the fibers may be provided with a binding agent and/or a moisture resistance agent. In preferred embodiments the nonwoven adsorber web is a fiber mixture of 80 parts polyester fibers, 20 parts viscose rayon staple fibers, and 20 parts polyvinyl alcohol fibers or a fiber mixture of 50 parts viscose rayon staple fibers and 50 parts linters, which are provided with an epichlorohydrin resin binder. The adsorber webs can be used to detect gaseous or particulate trace contaminants in air or another gas stream.

Adsorber material, apparatus and process for concentrating and

A micromechanical structure with cavities, containers, openings, canals, depressions, humps or the like for examinations of sample substances for possible changes of physical and/or chemical properties with targeted evaluation and documentation for the purposes of biotechnology, gene technology, cell and immune research and other medical, agricultural and environment research, where the structure consists of semiconducting material (of the group III to V of the elements of the periodic system) or contain the latter or glass or ceramic, diamond, or carbon and is made by a masking technique, especially by a chemical etching technique.
