Patent number: 8685746Abstract: A system and method for preparing and analyzing samples. The system can include a sample preparation system and a sample detection system coupled to the sample preparation system. The sample preparation system can include a deformable self-supporting receptacle comprising a reservoir adapted to contain a liquid composition comprising a source and a diluent. The sample detection system can be positioned in fluid communication with the reservoir, and can be adapted to analyze a sample of the liquid composition for an analyte of interest. The system can further include a fluid path defined at least partially by the reservoir and the sample detection system. The method can include applying pressure to the deformable self-supporting receptacle to move a sample of the liquid composition in the fluid path to the sample detection system, and analyzing the sample for the analyte of interest with the sample detection system.Type: GrantFiled: November 19, 2008Date of Patent: April 1, 2014Assignee: 3M Innovative Properties CompanyInventors: Kurt J.
