CIA Advantage-xr

Cryogen-free automation for high-performance canister & bag analysis

UNITY–CIA Advantage-xr™ is an advanced, inert system for the automated analysis of VOCs in whole air. It has multi-channel capacity and operates cryogen-free.

Who uses the CIA Advantage-xr?

UNITY–CIA Advantage-xr is the ideal solution for laboratories needing a robust, high-throughput system for canister analysis by US EPA Method TO-15 and Chinese EPA Method HJ 759, while retaining the capability to run sorbent tubes (US EPA Method TO-17) or carry out on-line monitoring.


Product benefits

  • Reduce running costs by avoiding the need for expensive and hazardous cryogen, and the associated risk of ice blockage of the flow path.

  • Enhance throughput by simultaneously analysing very volatile organic compounds and polar species in humid samples using Dry-Focus3™ technology.

  • Peace of mind – With unsurpassed analytical performance, UNITY–CIA Advantage-xr delivers the high-quality air monitoring results you demand.

  • Expand your capabilities – Run multiple samples/standards, from sub-ambient pressure to 50 psig, at a range of concentrations, ppt to %, with addition to the focusing trap via loop or metered volumes.

  • Future proof your lab – Incorporating method-compliant tube desorption and on-line sampling capabilities, CIA Advantage-xr allows you to respond to new applications and analysis requirements.
  • Easy and intelligent operation – With built-in parameters for several standard methods, automated self-checking diagnostics, and usage/maintenance counters, you can quickly and easily get going and keep going.

  • Be confident – you are buying state-of the-art, TO-15 (TO-15a) and HJ 759 compliant canister automation from the world’s leading manufacturer of air monitoring equipment.


  • Cryogen-free operation reduces running costs and increases lab safety.

  • Up to 27 inert channels and overlap mode allows fast, round-the-clock, automated operation.

  • Fully compliant with US EPA Method TO-15(A) and Chinese EPA Method HJ 759.

  • High-concentration and trace-level samples or standards can be run in the same sequence, or even stacked into the same run.

  • Low-pressure and sub-ambient samples can be run without needing pressurisation.

  • Splitless to high-split analysis for optimum sensitivity and sample flexibility.

  • Canister/whole-air and sorbent tube analysis all on one system, with the option to increase the tube automation to 100 tubes.

  • Unsurpassed water management – Dry-Focus3 three-stage focusing incorporates the Kori-xr water-removal module to enhance performance for humid air streams, without using liquid cryogen.

  • Heated inert internal lines and efficient purging combine to eliminate carryover between samples.

  • Advanced software control – Markes Instrument Control (MIC) is the only software designed specifically for thermal desorption users. Get the most out of your instrument with features including automated intelligent diagnostics, leak isolation, usage/maintenance counters, rapid method set-up and customisable limits.

  • Compatable with all major makes of GC and GC–MS, enabling easy integration into any laboratory.
