摘要： The invention relates to a gas dehydration membrane comprising a membrane having pores communicating between a first and an opposing second surface of the membrane and further having an average pore diameter on the first surface of the membrane which is about 10 to 1000 times smaller than that on the opposing second surface of the membrane. The invention further relates to a process for dehydrating a gaseous feedstock comprising passing the gaseous feedstock over a membrane characterized by high surface porosity wherein pore openings on a first surface thereof are at least 10 to 1000 times smaller than pore openings on an opposing surface thereof and wherein from about 2% to about 30% of the pore volume is occupied by a humectant.

摘要： The subject invention relates to a process for the selective separation of at least one component of a gaseous feedstream comprising passing the feedstream containing the component through a separation unit, the separation unit containing a porous membrane having a feed side and a permeate side, and a pore size of from about 10 Angstroms to about 200 Angstroms, and having disposed in the pores of the porous membrane a facilitator liquid comprising a carrier dissolved in a suitable solvent, including:a) dissolving the component in the facilitator liquid on the feed side of the porous membrane at the feed gas/membrane interface;b) forming a component-carrier complex;c) diffusing the complex to the permeate side of the porous membrane; andd) releasing the component from the carrier.The invention further relates to a membrane for the selective separation of at least one component of a gaseous feedstream comprising a porous membrane, having pores of from about 10 Angstroms to about 200 Angstroms, the pores containing a facilitator liquid having an affinity for the component to be selectively separated, the membrane being capable of operating at a transmembrane pressure of about 100 psig to about 300 psig.The subject invention also relates to use of the above-identified process and membrane for the separation of vapor phase olefins from olefin-containing feed streams.

摘要： The present invention provides compositions and methods for efficient recovery of nucleic acids, in particular DNA, from storage media. The present invention provides a method for using an alkaline elution buffer and mechanical agitation to elute nucleic acids from dried samples on storage media at room temperature. In particular, the present invention provides a method for room temperature recovery of DNA, including double stranded DNA (dsDNA) and single stranded (ssDNA), from storage media. The eluted DNA is suitable for numerous downstream applications

摘要： A system and method operative in accordance with the present disclosure facilitate storage and retrieval of individual or discrete samples of biological, non-biological, and chemical material stored on dry media. Sample material may be disposed upon or within a porous or solid (i.e., non-porous) sample storage medium and subsequently archived in, and retrieved from, storage elements such as multi-well plates, for example, using robotic devices or other automated apparatus. The disclosed system and method enable ejection of sample material from a sealed storage element into a specific well of a multi-well daughter plate, or into a specific cuvette, test tube, or similar container. In some embodiments, a sample carrier comprising a storage medium may be punched or ejected through a first seal of the storage element with an apparatus or implement such as a disposable piercing tip, for instance, inserted through a second seal of the storage element.
