Apex IR

The Apex IR has been developed for Isotope Ratio analysis. It has a quartz flow path and includes an additional mixing chamber that further homogenizes and stabilizes the sample aerosol stream, resulting in a more stable signal from the ICP-MS.

  • Improves sensitivity 3—10 fold depending on sample flow rate.
  • Enhanced stability, most stable system on the market
  • Supplied with 2 PFA MicrFlow nebulizers
  • O-ring free Quartz sample flow path
  • Flow rates from 20—600µL/min
  • Dual preset temperature settings for heater (100°C / 140°C) and cooler
    (-3°C / +2°C)
  • Nitrogen addition control
  • Upgrade with Membrane Desolvation
  • Retrofit to Apex Q version
