Market-leading advantages of UNITY–ULTRA-xr

• 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.
• Sample Security – With quantitative sample re-collection for repeat analysis, UNITY–ULTRA-xr offers simple method/data validation and overcomes 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.
• Versatility – Additional modules allow automated sequencing of canisters, bags and on-line samples – making UNITY–ULTRA-xr the perfect platform for expansion as the needs of your lab grow.
• Time saving – Capacity for up to 100 tubes and the ability to use overlap mode allow you to maximise productivity (for example, by running samples unattended all weekend).
• Broadest available tube analyte and concentration range – UNITY–ULTRA-xr is compatible with analysis of VOCs from C₃to C₄₄, including reactive and thermally labile species. The unbeatable split versatility (true-splitless to 125,000:1) also enables both high-concentration and trace-level samples to be analysed.
• Precision – Automated addition of an internal standard to the focusing trap or to a tube, during analysis enhances the quality of your data.
• High data quality – Automatic leak tests carried out before analysis of each sample ensure confidence in your data quality and full compliance with key regulated methods.
• Reliability – Dry-purge or pre-purge automatically remove water and air from the sample before analysis, avoiding the risk of interference in the gas chromatograph, and extending the lifetimes of your column and detector.
• Simplified chain of custody – The on-board TubeTAG read/write functionality automatically updates tube and sample information during analysis.
• 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.
• Easy laboratory integration – UNITY–ULTRA-xr is compatible with GC and GC–MS from all major manufacturers, minimising the upfront investment required to investigate new TD markets for your lab.
• Easy and intelligent operation – Built-in standard-method parameters, automated self-checking diagnostics and usage/maintenance counters maximise instrument uptime.
