730040Multi sensing of diagnostic components in breathClosedLegacy RDA Grant for R&DInnovate UKWe intend to develop a portable, rapid and economical point-ofcare test to determine the state of a testee's digestive health. This project will deliver a prototype to quantify hydrogen, methane and ammonia in a single measurement and most importantly will be calibration-less. The device will be evaluated with samples of exhaled air from sufferers of digestive disorders. The long-term aim is to develop a platform technology.
