Feature Internal pump to supply scrubbed air to carrier stream Through-port Diverter valves
Carrier Flow Recommended range 100-1200 mL/min, must be supplied and measured externally Fixed at 80 cc/min or 175 cc/min depending on model Nominal flow rate 100 sccm Fixed at 80 cc/min or 175 cc/min depending on model Nominal flow rate 100 sccm Fixed at 80 cc/min or 175 cc/min depending on model Fixed at 80 cc/min or 175 cc/min depending on model Nominal flow rate 100 sccm
Automation *** Basic:
  • Provides continuous dilution
  • Maintains a constant carrier flow through the permeation chamber
 Intermediate/ extended concentration range:
  • In the zero mode, scrubbed dilution flow is delivered to the outlet, allowing the end user to establish zero before sampling
  • Full range of mode capability
 Dual chamber:
  • Two separate permeation chambers with independent temperature control systems
  • Chamber 1 and chamber 2 can run independently, or be used together to combine trace components
  • Solenoid valves allow the carrier flows to be switched from the dilution stream to a vent port, allowing chamber 1, char[1]

*or 2°C above ambient, whichever is higher
** MFC = Mass flow controller

*** For all automated models (235, 345, 505):

  • User sets either the flow rate or the concentration via touch screen
  • Required temperature and concentration or flow rate or set and controlled automatically
  • External gas source
