Patent number: 11958049Abstract: A sample loading cartridge (1) for a microfluidic device comprises a cartridge body (10) with a sample reservoir (20) configured to house a volume of a liquid sample (3) and a sample port (30) in connection with the sample reservoir (20). The cartridge (1) also comprises an output channel (40) extending from the sample reservoir (20) and a feedback channel (50) connected to the sample reservoir (20) and to the sample port (30). The cartridge body (10) comprises a detection portion (60) aligned with the feedback channel (50) to enable detection of any sample (3) in the feedback channel (50). The flow resistance of the feedback channel (50) is lower than the flow resistance of the output channel (40) to cause liquid sample (3) received in the sample port (30) to enter the feedback channel (50) with substantially no liquid sample (3) entering the output channel (40).Type: GrantFiled: September 20, 2019Date of Patent: April 16, 2024Assignee: ASTREGO DIAGNOSTICS ABInventors: Johan Öhman, Martin Lovmar, Lovisa Söderberg, Mikael Olsson

Publication number: 20230265031Abstract: A method of purifying raw methanol obtained in chemical pulping, wherein heavy oil is admixed with the raw methanol to prevent precipitation, and the methanol mixture is distilled or evaporated to recover the methanol. The heavy oil is formed by mixing and heating raw methanol obtained from a side stream of chemical hardwood pulping with an acidic aqueous solution to vaporize low boiling point sulfurous compounds and provide acidified raw methanol. The acidified raw methanol is separated into a liquid top phase, a liquid aqueous middle phase, and a liquid bottom phase. The liquid bottom phase is extracted to obtain the heavy oil.Type: ApplicationFiled: June 17, 2021Publication date: August 24, 2023Inventor: Johan OLSSON
