Highly Sensitive and Selective Detection of Hydrogen Using Pd-Coated SnO(2) Nanorod Arrays for Breath-Analyzer Applications
We report a breath hydrogen analyzer based on Pd-coated SnO(2) nanorods (Pd-SnO(2) NRs) sensor integrated into a miniaturized gas chromatography (GC) column. The device can measure a wide range of hydrogen (1–100 ppm), within 100 s, using a small volume of human breath (1 mL) without pre-concentrati...

description | We report a breath hydrogen analyzer based on Pd-coated SnO(2) nanorods (Pd-SnO(2) NRs) sensor integrated into a miniaturized gas chromatography (GC) column. The device can measure a wide range of hydrogen (1–100 ppm), within 100 s, using a small volume of human breath (1 mL) without pre-concentration. Especially, the mini-GC integrated with Pd-SnO(2) NRs can detect 1 ppm of H(2), as a lower detection limit, at a low operating temperature of 152 °C. Furthermore, when the breath hydrogen analyzer was exposed to a mixture of interfering gases, such as carbon dioxide, nitrogen, methane, and acetone, it was found to be capable of selectively detecting only H(2). We found that the Pd-SnO(2) NRs were superior to other semiconducting metal oxides that lack selectivity in H(2) detection. Our study reveals that the Pd-SnO(2) NRs integrated into the mini-GC device can be utilized in breath hydrogen analyzers to rapidly and accurately detect hydrogen due to its high selectivity and sensitivity. |
