Versatility and performance

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
