Abstract

L'invention concerne un appareil de spectroscopie de plasma induit par laser pour l'analyse de liquides en écoulement optimisé afin d'éliminer l'effet splashing due à l'émission de gouttelettes du liquide en direction des fenêtre optiques du laser et de la lentille de collection de la lumière du plasma induit.
