Gas chromatography thermal desorber UNITY–ULTRA-xr Pro™

UNITY–ULTRA-xr Pro™ is our highest capacity, automated thermal desorption system for the unattended processing of up to 199 sorbent tubes in a single sequence. Its automated re-collection of tube and trap desorption split flows is unique to Markes and provides the most comprehensive re-collection options and enhanced sample security. It is ideal for laboratories needing to rapidly process large numbers of tube-based samples and take full advantage of the ability to automate sample re-analysis. UNITY–ULTRA-xr Pro is also available with Markes’ award winning Multi-Gas functionality, independently certified for operation with a choice of 3 carrier gases: helium, nitrogen and hydrogen. Hydrogen carrier gas offers fast, cost-effective analyses and protection against future helium shortages. Eliminate helium dependency – Use of hydrogen, nitrogen or helium as a carrier gas for your automated sorbent tube analysis with Markes' Multi-Gas UNITY–ULTRA-xr Pro. Sample security – With fully automated quantitative sample re-collection from all split flows, UNITY–ULTRA-xr Pro offers sequenced repeat analysis, simple method/data validation, as well as overcoming the ‘one-shot’ limitation of historical systems. Additionally, tubes remain capped at all times, avoiding sample contamination and/or analyte loss. Cost saving – The electrically-cooled focusing trap eliminates the expense and hassle of liquid cryogen and prevents risk of ice blockages thus optimising uptime. Choosing to operate with hydrogen carrier gas with a Multi-Gas thermal desorber will also eliminate dependency on helium and its rising cost.
