The UNITY-xr™ Thermal Desorber from Markes International offers state-of-the-art functionality and excellent analytical performance for the simultaneous analysis of VOCs, SVOCs and thermolabile compounds collected on sorbent tubes, canisters or sample bags.
The UNITY-xr™ system is perfect for research laboratories, laboratories with low throughput requirements and those who are new to the potential of thermal desorption.
The UNITY-xr Desorber is also available with Multi-Gas functionality.
The UNITY-xr Multi-Gas is the only single tube thermal desorber optimized and independently certified for operation with 3 carrier gases: helium, nitrogen and hydrogen. (Hydrogen as a carrier gas provides fast, cost-effective analysis and protection against future helium shortages.)
Key Features:
- 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: 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.
