The ULTRA-xr is a 100-tube autosampler for high-productivity analysis of trace-level VOCs and SVOCs by thermal desorption with GC or GC–MS.



  • Automated processing of up to 100 tubes with minimal operator intervention
  • Overlap mode to minimise analytical cycle times
  • Automated re-collection of outlet split flow – by adding one ULTRA-xr to a UNITY-xr
  • Automated re-collection of outlet and inlet split flows – by adding two ULTRA-xr units to a UNITY-xr (a capability that is unique to Markes)
  • Quantitative recovery and re-collection of C2 to C44 (including reactive and thermally labile species), from percent to sub-ppt concentrations
  • Tube capping (DiffLok™ caps) preserves the integrity of every sample
  • Operation fully compliant with a range of international standard methods
