Spectrophotomètre d'absorption atomique (AAS) UFX-210
FONCTIONNALITÉS:
Technique innovante d'analyse à la flamme riche oxygène-air-acétylène
La technique brevetée d'analyse de la flamme qui utilise la flamme riche oxygène-air-acétylène en remplacement de la flamme oxyde nitreux-acétylène pour les analyses d'éléments à haute température, telles que Ca, Al, Ba, W, Mo, Ti, V, etc. La température de la flamme est continue réglable entre 2300-2950 ℃, ce qui permet de choisir la meilleure température d'atomisation pour différents éléments. Il présente une utilisation facile, un faible coût d’analyse et une plage d’analyses AAS à large flamme. La flamme riche en oxygène ne pollue pas l'environnement et n'est pas nocive pour le corps humain. C'est une percée dans l'analyse AAS de flamme.
Système d'atomisation à flamme / four à graphite intégré, modifiable avec brûleur à émission de flamme
Système de contrôle précis entièrement automatisé
Analyse fiable entièrement automatique du four de graphite
Mesures de sécurité parfaites
