L'analyse des gaz, qui demandait habituellement des mois de travail au laboratoire, peut aujourd'hui être effectuée en un temps record sur le terrain. Une équipe de l'Eawag a mis au point un spectromètre de masse portatif qui permet d'analyser les gaz sur place. L'invention a maintenant donné naissance à une nouvelle entreprise spin-off.
Quels sont les effets des gaz volcaniques dans le lac africain du Kivu ? Comment le système d'aquifères du Rhin à Pratteln fonctionne-t-il ? Comment faire en sorte qu'une décharge d'ordures ménagères produise le moins possible de gaz à effet de serre ?
