UNITY-xr™ is a versatile analytical thermal desorption instrument for GC and GC/MS. It offers analysis of trace-level volatile and semi-volatile organic compounds (VOCs and SVOCs) in air and materials. In contrast to other thermal desorption units, UNITY-xr quantitatively re-collects samples for re-analysis or storage, enhancing sample security. UNITY-xr also features an electrically cooled cold trap, dispensing with the expense and inconvenience of liquid cryogen.

Features

• Quantitative sample re-collection of all the split flows enables repeat analysis of critical samples and easy method validation
• An inert, optimised flow path allows quantitative recovery of C2 to C44, including reactive and thermally labile species… from percent to sub-ppt concentrations
• As well analysing 3½″ standard TD tubes, the UNITY-xr facilitates analysis of on-line, canister and bag samples through the modular addition of versatile accessories
• Rapid operation of the electrically-cooled focusing trap reduces costs and ensures fast sample throughput
• Method-compliance is aided by tube- and leak-testing, water management, and addition of internal standards
• Samples are easily tracked with barcoded tubes and RFID TubeTAGs
• Compatible with all major makes of GC and GC–MS
