Abstract: A protective floor film adhesive composition includes an acrylic pressure sensitive adhesive having an inherent viscosity in a range of 0.3 dl/g or greater, a cross-linker, and a plasticizer compatible with the acrylic pressure sensitive adhesive. The adhesive composition has a glass transition temperature of ?10 degrees Celsius or less, and the adhesive composition has an initial 180 degree peel adhesion test value of 5 oz/in or greater and builds to a final 180 degree peel adhesion test value of 40 oz/in or less, and a haze test value of 10% or less. Protective floor film articles and methods of protecting flooring are also described.

Abstract: A single pass simulated moving bed apparatus and methods are described for continuously separating a target molecule from a liquid mixture, using a simulated moving bed system. The simulated moving bed system includes a plurality of filter cartridge modules in serial fluid communication. Each filter cartridge module includes a volume of stationary phase particulates adjacent a porous substrate layer. The volume of stationary phase particulates has a bed height of less than 1 centimeter.

Abstract: A composite filter medium comprising a filter element comprising at least one porous fibrous filtration layer, and at least one layer of a sorbent, stationary phase particulates selected from organic or inorganic particulates having an average diameter of less than 50 micrometers, soft particulates, and ground monolithic particulates. The particulates are capable of binding target molecule by, for example, adsorption, ion exchange, hydrophobic binding, and affinity binding. The particulates provide higher binding capacities than can be achieved using filter media incorporating conventional process scale chromatography resin particulates.
