Multi-fluidic cartridges for sample analysis and methods for using same
First Claim
1. A multi-fluidic cartridge for sample analysis, comprising:
- (a) a first conduit beginning at a sample entry port for receiving a fluid sample and in fluid communication with one or more sensors, wherein said first conduit includes a capillary stop oriented between said sample entry port and said one or more sensors;
(b) a plurality of rupturable fluidic pouches, each containing a different fluid and in fluid communication with a respective delivery conduit configured for delivering a respective fluid to said first conduit; and
(c) at least one pneumatic pump configured to move said fluid sample to said one or more sensors and for transporting at least one of said different fluids to said first conduit.

16. A process for analyzing a fluid sample with a multi-fluidic cartridge, comprising:
-
(a) introducing said fluid sample into a sample entry port and allowing said fluid sample to enter a first conduit beginning at said sample entry port and in fluid communication with one or more sensors, wherein said first conduit includes a capillary stop oriented between said sample entry port and said one or more sensors, and wherein operation of a pump causes said fluid sample to pass through said capillary stop and to said one or more sensors; (b) rupturing a plurality of fluidic pouches, each containing a different fluid and in fluid communication with a respective delivery conduit configured for delivering said fluid to said first conduit; (c) transporting said different fluids through said delivery conduits and to said first conduit; (d) transporting said fluid sample through said first conduit and over said one or more sensors; and (e) analyzing said fluid sample at said one or more sensors for the presence or concentration of an analyte or a property of said fluid sample. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
