1. 1. Simultaneous detection of potassium, water vapor and temperature with tunable diode laser absorption spectroscopy

   Master-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Edvin Norén; [2015]
   Nyckelord :TDLAS; DAS; WMS; Simultaneous detection; Measurement; Potassium; Water vapor; Temperature; Biomass; Optics;

   Sammanfattning : Existing tunable diode laser absorption spectroscopy (TDLAS) sensors for potassium (K) and for water vapor (H2O) and temperature were combined to enable simultaneous measurements in combustion and gasification processes. In-situ real-time detection of the above mentioned combustion parameters will improve the understanding of ash-formation during thermochemical conversion of biomass. LÄS MER

3. 2. Application of Diode Laser Molecular Absorption Spectroscopy for Studies of Gas Concentrations in Food Packages

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Författare :Jan Von Keitz; [2014]
   Nyckelord :Diode Laser Spectroscopy Gas Concentration Food Packages; Physics and Astronomy;

   Sammanfattning : When it comes to absorbing and emitting radiation, molecules show similar properties as atoms do. A signicant dierence though, is that a molecular spectrum consists of notably more absorption lines compared to an atomic spectrum. LÄS MER
