Abstract

We studied the sensing performance of the thermoelectric hydrogen sensor (THS) aimed at application to the human breath hydrogen (H₂) analysis for the evaluation of colonic flora. The THS has unique gas sensing performance such as H₂ selectivity and immunity to humidity. We have designed a simple human breath analysis system with this sensor, gas pump and dehumidifier of silica gel. The humidity of the human breath gas was controlled to be as low as 20% RH at 25 °C through the gas-drying tube because the humidity in the human breath gas causes serious noise effect. The THS system was able to detect 4-103 ppm of H₂ in human breath sample which coexisted with various gases such as methane (CH₄) and carbon monoxide (CO).
