UNITY–CIA Advantage-xr Cryogen-free, automated canister and whole air preconcentration system


Benefits of UNITY-CIA Advantage-xr


  • Multi-Gas UNITY-xr – for the first time, enabling certified thermal desorption instruments to be run with a choice of carrier gases: helium, nitrogen and hydrogen.

  • Reduced running costs– The allows analysis of compounds as volatile as C2 hydrocarbons without the need for cryogen, and the associated risk of flow-path blockage with ice.

  • Enhance productivity – Up to 27 canisters or bags at high and low concentrations can be analysed in a single unattended sequence, with sample throughput boosted by overlap mode.

  • Method-compliance – Internal standard capability, outstanding system linearity and part-per-trillion-level MDLs ensure full compliance with key methods such as US EPA TO-15/TO-15A and Chinese EPA HJ 759.

  • Future-proof – Because it incorporates capability for on-line monitoring and sorbent-tube desorption, CIA Advantage-xr allows you to respond to new applications and customer requirements.

  • Unsurpassed water management – Dry-Focus3™ three-stage focusing incorporates the Kori-xr™ water-removal module to allow simultaneous analysis of in humid air streams, without using liquid cryogen.

  • Expanded sampling capabilities – Options for loop or metered addition enable a wide range of samples or standards to be run, with pressures from sub-ambient pressure to 50 psig, and concentrations from ppt to percent level.

  • Intelligent software – Uptime is maximised thanks to built-in parameters for several standard methods, automated self-checking diagnostics, and usage/maintenance counters.

  • Streamlined analysis – Heated internal lines and efficient purging combine to eliminate carryover between samples, meaning fewer blanks.

  • Broad system compatibility – The short, heated transfer line means that the UNITY–CIA Advantage-xr can be installed on all major makes of GC and GC–MS.
