Patent number: 8133438Abstract: A microfluidic device that comprises a microchannel structure in which there are one, two or more flow paths (101;201a,b;301a,a?,b) all of which comprises a porous bed I (104,204,304) that is common for all of the flow paths and exposes an immobilized reactant R that is capable of interacting with a solute S that passes through the bed. The characteristics are that at least one of the flow paths comprises/comprise a second porous bed II (105,205,305) that is placed upstream of porous bed I (104,204,304) and is dummy with respect to interaction with solute S but capable of interacting with a substance DS that is present in a liquid aliquot together with solute S and is capable of disturbing the result of the interaction between solute S and said immobilized reactant R. There is also disclosed a method utilizing the device and variant of the device in which the immobilized R is replaced with a generic affinity ligand LI and/or porous bed II exposes a generic ligand LII that may be different from LI.Type: GrantFiled: January 31, 2005Date of Patent: March 13, 2012Assignee: Gyros Patent ABInventors: Johan Engström, Mats Inganäs, Gunnar Thorsén

Patent number: 7776272Abstract: A liquid router that comprises an inlet microconduit that branches into two exit microconduits (microconduit I and II) and is present in a microchannel structure of a microfluidic device which is using centrifugal force created by spinning the device about a spin axis for transporting liquid. The router is characterized in comprising a microcavity in which there are: a lower part comprising two exit openings (exits I and II), and an upper part comprising an inlet opening to which the inlet microconduit (3) is connected, and microconduits I and II which are connected to exits I and II, respectively, and stretch from a shorter radial position to a larger radial position relative to the spin axis. Microconduit II has a reduced hydrophilicity (=reduced apparent wettability) compared to microconduit I.Type: GrantFiled: October 1, 2004Date of Patent: August 17, 2010Assignee: Gyros Patent ABInventors: Gunnar Ekstrand, Gunnar Thorsen

Patent number: 7429354Abstract: A microfluidic device that comprises several microchannel structures in which there are an inlet port, an outlet port and therebetween a substructure comprising a fluidic function. The device has an axis of symmetry around which the microchannel structures are arranged as two or more concentric annular zones. for an inlet port and an outlet port of the same microchannel structure the inlet port is typically closer to the axis of symmetry than the outlet port. Each microchannel structure comprises a substructure that can retain liquid while the disc is spun around the axis and/or the inlet ports are positioned separate from the paths waste liquid leaving open waste outlet ports will follow across the surface of the disc when it is spun. For the microchannel structures of an annular zones the corresponding substructures are at essentially at the same radial distance while corresponding substructures in microchannel structures of different annular zones are at different radial distances.Type: GrantFiled: March 19, 2002Date of Patent: September 30, 2008Assignee: Gyros Patent ABInventors: Per Andersson, Gunnar Ekstrand, Ulrike Selditz, Sussanne Wallenborg, Helene Derand, Gunnar Thorsen, Ebru Togan-Tekin

Publication number: 20070086926Abstract: A microfluidic device which comprises two or more microchannel structures (set 1), each of which comprises a structural unit which comprises (i) one or more inlet microconduits, and (ii) an outlet microconduit downstream said one or more inlet microconduits, and (iii) a flow path for a liquid passing through either of said inlet microconduits and said outlet microconduit. The device is characterized in that each outlet microconduit in said two or more microchannel structures is a restriction microconduit. There may also be a microcavity between the inlet microconduit(s) and the restriction microconduit in each microchannel structure. Typically common flow control is used for driving a liquid flow within the device. The innovative design is useful for creating flow with low inter-channel variation with respect to the microchannel structures of the device.Type: ApplicationFiled: September 12, 2006Publication date: April 19, 2007Inventors: Per Andersson, Gunnar Thorsen, Gunnar Kylberg

Patent number: 4200504Abstract: Process for extraction and separation of metals utilizing the advantages of liquid-liquid extraction with cation exchangers without requiring the equivalent addition of alkali. The process is based on a combination of leaching the metal-containing raw materials with an organic acid (cation exchanger) and a subsequent use of the formed metal cationic complex in a liquid-liquid extraction process. In the said extraction process, the organic solution of metal complexes is used to recover and separate metal ions from an aqueous solution of metal salts.Type: GrantFiled: February 14, 1977Date of Patent: April 29, 1980Inventor: Gunnar Thorsen
