摘要：
Various devices are disclosed for measuring the concentration of an analyte, such as acetone, in a breath sample. The disclosed devices include a disposable cartridge containing a reactive material that extracts the analyte from a breath sample passed through the cartridge. In some embodiments, the cartridge contains a solid, porous structure (such as a disk, bowl or puck) that contains the reactive material. To induce a chemical reaction for measuring the quantity of the extracted analyte, the porous structure may be brought into contact with a sponge or pad that dispenses developer solution to the porous structure. Also disclosed are devices for routing a breath sample through the cartridge during exhalation, and for analyzing a reaction in the cartridge to measure a concentration of the analyte.
