Abstract
A flow cell system includes a housing, a mixing chamber and a flow channel sized to provide for movement of liquid from the mixing chamber by non-capillary action. A monitoring device is coupled to the matrix. A fluid moving source is coupled to the flow channel. A matrix is coupled to a distal end of the flow channel and contains a compound that will react with the sample to create a change detectable by the monitor device. A fluid path extends from the mixing chamber to the flow channel and to the matrix to bring sample fluid to the matrix for detection of analyte levels therein.
Claims64
A flow cell system, comprising:
- a housing;
- a mixing chamber;
- a flow channel sized to provide for movement of liquid from the mixing chamber by non-capillary action,
- a monitoring device coupled to the matrix;
- a fluid moving source coupled to the flow channel;
- and
- a matrix coupled to a distal end of the flow channel, containing a compound that will react with the sample to create a change detectable by the monitor device, wherein a fluid path extends from the mixing chamber to the flow channel and to the matrix bring sample fluid to the matrix for detection of analyte levels therein.
A method for analyzing a sample for the presence of an analyst, comprising:
- introducing the sample into a test device that includes a non-microporus mixing chamber, flow channel and a matrix;
- flowing the sample from the mixing chamber through the flow channel to the matrix by non-capillary flow;
- and
- contacting the sample with the matrix containing a compound that will react with the sample;
- and
- detecting a change in the sample with a monitor device.
