DETERMINAZIONE RAPIDA DI MERCURIO IN APPLICAZIONI ANALITICHE

LabAnalyzer 254

Il LabAnalyzer è la perfetta soluzione per la determinazione quantitativa di mercurio in campioni acquosi e campioni digestati in laboratorio.

Contrariamente ai tipici multi-elemento AAS, il LAbAnalyzer 254 è appositamente progettato per il mercurio elementare. Questo permette prestazioni di vertice nelle applicazioni analitiche. L’uso di lampade a mercurio altamente stabili appositamente sviluppate assieme a sensori UV a temperatura controllata permette un limite di rilevabilità di qualche ppt.

  • the optical system does not require any readjustment
  • Short analysis time
  • Low reagent consumption
  • Automatic zero adjustment
  • Memory effects are minimized and a high sample throughput is possible thanks to specially selected materials for sample gas conducting components and heating of the optical bench.
  • For analyses according to DIN 38406-12 / EPA 7470A / EPA 7471A)
  • Measuring range:0.01 ppb … 10 ppb (10 ng/l to 10 µg/l)
  • Hg trap: Mercury vapors cannot escape into the lab
