Agilent 7900 replaces the 7700 series device to continue the best traditions of single-quad ICP/MS

Specification

 

  • New interface and ion lenses for an up to 15-fold improved signal/noise ratio
  • New patented detector with an 11-order dynamic range and 0.1 ms response time
  • The new Ultra HMI for analyses of salt solutions of up to 25% TDS with no preliminary dilution
  • New ORS4 for gas change in less than 3 sec
  • New ISIS-3 for fast launch, auto optimization and sample introduction
  • No maintenance required for the cones and lenses even after 8 hours of continuous work
  • New MassHunter 4.1 - now even easier!
  • Remote App monitor (iOS and Android devices, tool status viewing and basic system functions control)
