Sample preparation container and method

A system for preparing samples and analyzing samples for an analyte of interest, the system comprising:

• a sample preparation system comprising:
• a freestanding container comprising a first reservoir,
• a deformable self-supporting receptacle dimensioned to be received in the first reservoir of the freestanding container and comprising a second reservoir, the freestanding container being more rigid than the deformable self-supporting receptacle, the second reservoir adapted to contain a liquid composition comprising a source and a diluent;
• a sample detection system coupled to the sample preparation system, the sample detection system positioned in fluid communication with the second reservoir of the deformable self-supporting receptacle, the sample detection system adapted to analyze a sample of the liquid composition for the analyte of interest;
• and
• a fluid path defined at least partially by the second reservoir and the sample detection system.

A method for preparing samples and analyzing samples for an analyte of interest, the method comprising:

• providing a liquid composition comprising a source and a diluent;
• providing a sample preparation system comprising a deformable self-supporting receptacle dimensioned to be received in a freestanding container, the freestanding container being more rigid than the deformable self-supporting receptacle, the deformable self-supporting receptacle comprising a reservoir;
• providing a sample detection system coupled to the sample preparation system and in fluid communication with the reservoir;
• providing a fluid path defined at least partially by the reservoir and the sample detection system;
• positioning the liquid composition in the reservoir;
• 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.
