    摘要： A large class of crosslinked cyclodextrin resins soluble in water to an extent under about 200 ppm but soluble in an organic solvent to an extent of at least 0.1 weight percent have good film-forming properties with a wide variety of solid phase substrates. The films exhibit excellent adhesive properties toward virtually all solid surfaces which consequently can be readily coated with a thin film having a multiplicity of cyclodextrin moieties available at the surface for seperation and/or purification. Such coated substrates can be prepared in a variety of sizes, shapes, and cyclodextrin loading quite conveniently and relatively inexpensively.

    摘要： A support matrix which immobilizes enzymes by ion exchange forces comprises a core support deposited on which is a functionalized polyethylenimine insoluble in water. Such support matrices may be prepared from a virtually limitless variety of core supports since the functionalized polyethylenimines of this invention show excellent adhesive properties even to smooth surfaces. Such support matrices are particularly useful where the enzyme to be immobilized has a rather limited inherent half-life. The functionalized polyethylenimine is a carboxylic acid amide of polyethylenimine, a sulfonic acid amide of polyethylenimine or polyalkylated polyethylenimine.

    摘要： Organic-inorganic support matrices for immobilized enzymes comprise a solid, porous, inorganic, water insoluble support combined with a copolymeric material resulting from the reaction of aminopolystyrene and a bifunctional monomer. The matrix is prepared by depositing a salt of amino-polystyrene within the pores of the solid support from an aqueous solution at a pH less than 7 after which the resulting composite is then reacted with an excess of a bifunctional reactive monomer thus forming a copolymeric organic material in situ substantially entrapped in the pores of the support and containing functionalized pendent groups to which an enzyme may be coupled to form an immobilized enzyme conjugate.

    摘要： Support matrices for immobilized enzymes which comprise a combined organic-inorganic support may be prepared by treating a solid, porous, inorganic, water-insoluble support such as an inorganic porous metal oxide with a styrene monomer, polymerizing the styrene on the solid support at polymerizing conditions, nitrating the resultant polystyrene-solid support composite and thereafter reducing the nitrated polystyrene-solid support composite to form an aminopolystyrene-solid support matrix.

A coating is disposed on the exterior surface of the shaped tip portion and the coating comprises a transition metal compound or a combination of transition metal compounds, and an alkali metal compound. A center electrode extends through the central axial bore of the insulative sleeve. A metal sleeve is provided, wherein the insulating sleeve is positioned within, and secured to, the metal shell. A ground electrode is coupled to the metal shell and positioned in a spaced relationship relative to the center electrode so as to define a spark gap.
