Abstract
A method of determining the concentration of an analyte of interest in breath. The method includes obtaining a disposable cartridge comprising a reaction chamber, a liquid chamber, and a window to permit determination of a color intensity in the reaction chamber, directing a volume of breath into the cartridge, and initiating a sequence whereby liquid is released from the liquid container into the reaction chamber to cause a reaction which produces a change in the intensity of a color viewable through the window. The intensity of the color corresponds to the concentration of the analyte of interest. The reaction progresses through a kinetic phase and eventually reaches equilibrium. The sequence additionally includes measuring the intensity of the color at a point in the kinetic phase, to determine the concentration of the analyte of interest in breath.
