20120255894 | METHOD FOR COVALENTLY ATTACHING POLYMERIC MONOLITHS TO POLYETHER ETHER KETONE (PEEK) SURFACES - Method for covalently attaching polymeric monoliths to polyether ether ketone (PEEK) surfaces The present invention provides a method of covalently attaching a polymeric monolith to the internal surface of polyether ether ketone (PEEK) tubing and column housings, comprising the steps of: (a) reducing the ketone group of the PEEK to a hydroxyl group to obtain a modified PEEK, (b) optionally reacting the hydroxyl group obtained in step (a) with a compound having an active vinyl group to form a modified PEEK selected from the group of acrylate modified PEEK, methacrylate modified PEEK, styrene modified PEEK and epoxy modified PEEK, and (c) reacting the modified PEEK obtained in step (a) or (b) with a polymer or polymerization mixture for forming the polymeric monolith. Hereby, the mechanical stability and solvent durability of larger diameter monolithic columns as well as their overall performance are improved. | 10-11-2012 |
20120180229 | METHOD FOR ENZYMATIC TREATMENT OF CELLULOSE-CONTAINING TEXTILES BY MEANS OF A SOLUTION THAT COMPRISES AT LEAST ONE CELLULASE TYPE - A method for enzymatic treatment of cellulose-containing textiles by means of a solution that comprises at least one cellulase type, characterized in that before the treatment with the cellulase-containing solution, an aqueous solution having a pH below 7 and containing at least one agent raising the swelling capacity of the solution, preferably a neutral salt solution, is applied to only some areas of the textile. | 07-19-2012 |
20110260063 | CHARACTERIZATION OF PHYSICOCHEMICAL PROPERTIES OF A SOLID - Procedure for determining the physicochemical properties of solids, wherein a solid is subjected to near-infrared spectroscopy, with simultaneously determining at least two characterization properties of the solid (FIG. | 10-27-2011 |
20100078572 | ANALYSIS OF LOW MOLECULAR WEIGHT MOLECULES BY MALDI-MS - The invention relates to a process for the analysis of molecules having a molecular weight of <1500 Da by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), wherein an analyte containing low molecular weight molecules is applied to a matrix material, which is characterized in that the matrix material comprises fullerene-derivatised silica. This process allows clear identification of small molecules through intensive signals without matrix -related background disturbances. | 04-01-2010 |
