Optogalvanic spectroscopy with microplasma sources – Current status and development towards Lab-On-A-Chip
2015 (English)Conference paper, Abstract (Refereed)
Miniaturized optogalvanic spectros-copy shows excellent prospects of becoming a highly sensitive method for gas analysis in micro total analysis systems. Here, a status report on the current development of microplasma sources for optogalvan-ic spectroscopy is presented, together with the first comparison of the sensitivity of the method to con-ventional single-pass absorption spectroscopy. The stability and reproducibility of the microplasma source when used as a detector for optogalvanic spectroscopy is also investigated, and a roadmap of future developments is presented, with the particular focus of integrating sensors for measuring the pres-sure, temperature and flow of the sample gas through the detector, and combining the detector with a miniaturized combustor to allow for studies of solid samples.
