Claim 0:
1. A breath sample analysis cartridge, comprising:
a cartridge body that houses an interactant and a compressible reservoir that holds a volume of developer solution, said compressible reservoir comprising an absorbent material pre-soaked with said developer solution; and
a piston slidably mounted within the cartridge body, the piston slidable from a first position in which the piston does not apply a compressive force to the compressible reservoir to a second position in which the piston applies a compressive force to the compressible reservoir, wherein the compressive force causes the developer solution to flow from the compressible reservoir into the interactant;
wherein the piston and cartridge body are configured to cause the piston to lock into said second position such that the piston continues to apply said compressive force to the compressible reservoir once the piston is advanced to the second position.
