With emerging technologies, which result in more intensive industry and manufacturing, fully portable and multi-gas detectors are increasingly being required on to handle situations where a wider range of hazardous substances may be present and proper detection equipment is essential. Most gas monitoring devices focus on a single species. However, there are many sensing applications (e.g.: industrial chemical processes) where several gases need monitoring at the same time and with a single detector. In this regard, a novel portable QEPAS (Quartz-Enhanced Photo-Acoustic Spectroscopy) multi-gas detector with non overlapping QTFs (Quartz Tuning Forks) resonance frequencies can help meet these challenges. |
