Analyse rapide du mercure dans les applications analytiques de laboratoire
LabAnalyzer 254
L’analyseur de laboratoire LabAnalyser 254 est utilisé pour déterminer la quantité de mercure présente dans des échantillons aqueux et des digestions aqueuses.
Contrairement à un AAS multi-éléments typique, le LabAnalyzer 254 est spécialement conçu pour mesurer le mercure élémentaire. Cela permet d’obtenir des performances optimales dans les applications analytiques. L’utilisation d’une lampe à mercure hautement stable spécialement développée en liaison avec des capteurs UV commandés par thermostat permet d’obtenir une limite de détection de quelques ppt de mercure.
