Markes UNITY–ULTRA-xr and Pro

Product benefits

• Enhance throughput – Capacity for up to 100/199 tubes and the use of sample overlap allow you to maximise productivity, e.g. unattended operation all weekend.

• Peace of mind – With automated quantitative sample re-collection for repeat analysis, UNITY–ULTRA-xr and Pro offers simple method/data validation and overcomes the ‘one-shot’ limitation of other systems.

• Expand your capabilities – Not only does TD100-xr and UNITY–ULTRA-xr Pro allow you to analyse the widest possible range of VOCs and SVOCs in a single run, but sample stacking increases sensitivity, and the unbeatable split range (splitless to 125,000:1) enables both high-concentration and trace-level samples to be analysed on the same instrument.

• Reduce running costs by avoiding the need for expensive and hazardous cryogen, and the associated risk of ice blockage of the flow path.

• Secure and reliable – Tubes remain capped at all times, thereby making automation mechanically simple and avoiding sample contamination and/or analyte loss.

• Simplify chain of custody and reduce errors with the on-board TubeTAG read/write functionality, which automatically updates tube and sample information during analysis.

• Easy and intelligent operation – With built-in parameters for several standard methods, automated self-checking diagnostics, and usage/maintenance counters, you can quickly and easily get going and keep going.

• Future-proof your lab – Adding further modules to the UNITY–ULTRA-xr allows automation of canisters or on-line samples, as well as extending tube automation up to 199 samples.

• Be confident – You’re using a desorber that complies with key standards set out by numerous regulatory bodies, including US EPA, Chinese EPA, CEN, ISO, ASTM, HSE, JSA, NIOSH, and more.

Features

• Automated, cryogen-free, unattended operation for up to 100/199 sample tubes.

• Quantitative sample re-collection enables repeat analysis of critical samples and easy method validation.

• Robust design accommodates industry-standard 3½″ tubes.

• Stacking of multiple tube samples on the focusing trap increases sensitivity for samples restricted by breakthrough or time limitations.

• An inert, optimised flow path allows quantitative recovery of C3 to C44, including reactive and thermally labile species... from percent to sub-ppt concentrations.

• Rapid operation of the electrically-cooled focusing trap reduces costs and ensures fast sample throughput.

• Method compliance is aided by leak-testing, water management and addition of internal standards.

• Samples are easily tracked with barcoded tubes and RFID TubeTAGs.

• Advanced software control – Markes Instrument Control (MIC) is only software designed specifically for thermal desorption users. Get the most out of your instrument with components such as automated intelligent diagnostics, leak isolation, usage/maintenance counters, rapid method set-up and customisable limits.
