1. A device, comprising:
a cartridge housing comprising a breath capture module; and
a rotary valve operatively coupling a mouthpiece with the breath capture module, the rotary valve having a valve body with a central aperture, the valve body coupled to the cartridge housing via a spring, the rotary valve having:
an open position where breath of a user can pass through the rotary valve, across capture sites of the breath capture module, and into a vacuum port; and
a closed position for sealing the breath capture module from fluid passing through the rotary valve, while allowing the breath capture module to be exposed to a reagent.
