摘要:
Die Erfindung betrifft ein Filterelement (10) zur Luftfiltration mit einer matrixförmigen Stützstruktur (1), welche eine Vielzahl von durch Kanalwände (12) voneinander getrennte Kanäle (11) aufweist und die mit einem feste Sorbentien enthaltenen Schüttgut (2) gefüllt ist. Das Schüttgut (2) kann ein Granulat aus Adsorbentien und/oder Absorbentien sein. Erfindungsgemäß ist die matrixförmige Stützstruktur (1) aus einem adsorbierenden Material gefertigt. Ein solches Filterelement weist in vorteilhafter Weise eine gute adsorbierende bzw. absorbierende Wirkung auf.
摘要:
A cationic composite filter aid may include a silicate substrate, a silica precipitated on the silicate substrate, and a cationic surface modification of the precipitated silica. A method for making a cationic composite filter aid may include providing a silicate substrate, precipitating a silica onto the silicate substrate to form a composite filter aid, and cationically modifying the precipitated silica to form a cationic composite filter aid. A method for filtering a liquid may include providing a liquid for filtering and filtering the liquid through a cationically modified composite filter aid. The cationically modified composite filter aid may include a silicate substrate, a precipitated silica, and a cationic surface modification of the precipitated silica.
摘要:
Guanidine-functionalized particles and methods of making and using such particles are provided, such as guanidine-functionalized metal silicate particles. A nonwoven article is also provided including a porous fibrous nonwoven matrix and guanidine-functionalized metal silicate particles enmeshed within the porous fibrous nonwoven matrix. The nonwoven article may be used, for instance, for removing microorganisms from an aqueous sample by contacting a fluid sample with the nonwoven article such that at least a portion of the microorganisms are removed from the fluid sample.
摘要:
The invention relates to a method (100) for processing a sample of biological material containing target cells and companion cells in order to extract nucleic acids of the target cells. The method (100) has a step (110) of accumulating the target cells of the sample by separating the target cells or the companion cells from the sample. The method (100) additionally has a step (120) of decomposing the target cells by chemical or physical lysis in order to produce a target cell lysate containing the nucleic acids of the target cells. The method (100) further has a step (130) of purifying the nucleic acids from the target cell lysate in order to extract the nucleic acid of the target cells.
摘要:
The invention relates to an activated carbon, in particular an activated carbon with reactive and/or catalytic activity, said activated carbon being in the form of discrete activated carbon particles, preferably in a spherical and/or grain form. The activated carbon is provided with and/or comprises at least one metal component which has at least one metal-containing ionic liquid (IL) containing, in particular metal ions, preferably based on a metal compound. The invention also relates to methods for producing said activated carbon, to the uses thereof and to materials provided therewith.
摘要:
Articles such as filter media, which include dendrimers and/or other components, are provided. The filter media may further include a water repellant (e.g., a fluorinated species) to impart desirable properties to the media such as high water repellency. The filter media may also have a high efficiency as a function of pressure drop (i.e., high gamma values). In some embodiments, the filter media includes a fiber web which may be formed of various components such as glass fibers. The fiber web can also include additional components such as synthetic fibers, binder components, as well as other additives. The media may be incorporated into a variety of filter element products.
