Market-leading advantages of UNITY-xr

• Eliminate helium dependency – Use of hydrogen, nitrogen or helium as a carrier gas with our  Multi-Gas UNITY-xr.
• Sample security – Unique among single tube desorbers UNITY-xr offers quantitative sample re-collection for repeat analysis, overcoming the one-shot limitation of historical TD systems and offering simple method/data validation.
• Cost saving – The electrically-cooled focusing trap eliminates the expense and inconvenience of liquid cryogenic cooling and removes the risk of ice blockages thus maximising uptime.
• Versatility – UNITY-xr can be combined with additional modules to allow automation of multiple TD tubes, canisters and/or on-line air/gas samples – making UNITY-xr the perfect platform for expansion as the needs of your lab grow.
• Broadest available application range on one TD platform – UNITY-xr is compatible with organic compounds ranging in volatility from C₂ to n-C₄₄ hydrocarbons plus reactive and thermally labile species. The unbeatable split versatility (splitless to 125,000:1) also enables both high-concentration and trace-level samples to be analysed.
• Compliance with standard methods – Stringent leak testing, re-collection and a range of advanced water management options ensure full compliance with key standard methods from numerous regulatory bodies, including US EPA, Chinese EPA, CEN, ISO, ASTM, HSE, JSA and NIOSH.
• Enhanced performance – An inert flow path and backflush trap desorption eliminate the risk of discrimination, minimise artefacts and optimise data confidence.
• Compatibility with GC and GC–MS from all major manufacturers – minimises the upfront investment required to investigate new TD markets for your lab. UNITY-xr can even be interfaced to direct MS instruments for high throughput targeted analysis.
• Easy and intelligent operation – Built-in standard-method parameters, automated self-checking diagnostics and usage/maintenance counters maximise instrument uptime.
