The ULTRA-xr Sampler combined with the ULTRA-xr Thermal Desorber UNITY–ULTRA-xr™ is Markes International's automated thermal desorption system for rapid, unattended analysis of up to 100 tubes/samples in a single sequence.
Additional options include autosamplers for canister, bag or on-line analysis.
The UNITY–ULTRA-xr is the ideal platform for high-throughput laboratories requiring the flexibility to expand their capabilities to extended analyte ranges and varied sample types while maximising sample throughput.
UNITY–ULTRA-xr is also available with Markes' award winning Multi-Gas functionality, independently certified for operation with a choice of 3 carrier gases: helium, nitrogen and hydrogen.
Hydrogen carrier gas offers fast, cost-effective analyses and protection against future helium shortages.
Key Features:
- 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 and intelligent operation: built-in standard-method parameters, automated self-checking diagnostics and usage/maintenance counters maximise instrument uptime.
