Abstract
We present VOGAS, a semi-portable in-strument performing non-invasive and fast detection of gastric cancer. The VOGAS device analyzes the patients exhaled breath using two gas sensing techniques: infrared spectrometry and different technologies of resistive gas sensors (gold nanoparticles, research developed metal oxides and commercial metal oxides). The combination of these techniques results in a great amount of complementary information in a single breath sample mea-surement, which can increase the ability of a one-gas sensing technique device to detect gastric diseases. In this work, we describe the VOGAS device in detail.
