Thermo Scientific - Trace GC Ultra

Year of introduction 1998
Status available
Company Thermo Scientific
Categories Chromatography: GC
The TRACE GC UltraTM is built around the recognized quality, reliability and ruggedness of the established TRACE GC. Ultra performance, reliability, and usability make this a must-have GC for any laboratory. Automated features result in a tremendous increase in sample throughput, with analyses performed up to 30 times faster than before, without compromises in precision.

Product detail
Built around the recognized quality, reliability and ruggedness of the established TRACE GC, the new Ultra platform incorporates innovative solutions, such as the new Ultra Fast and Large Volume splitless techniques, delivering unprecedented performance.

Ultra in speed of analysis
Featuring a linear heating rate of up to 1200 °C per minute, the TRACE GC Ultra is able to dramatically decrease sample run times in a wide range of GC applications from crude oils, pesticides and hydrocarbons determination, to drug screening and food and flavors characterization. Combined with conventional GC or MS detectors, this technique enormously increases lab productivity without compromising analytical resolution, precision or reliability.

Ultra in performance
The new Large Volume splitless technique, only available with the Ultra platform, extends the sample injection volume of conventional GC methods without requiring additional investment, further training, or the need to revalidate methods. This new capability results in dramatic increases in sensitivity, without incremental sample preparation costs in a large array of trace determinations, and is extremely easy to set-up and operate with a standard split/splitless injector.

Ultra in system usability
The new TRACE GC Ultra also supports a complete range of injectors, such as the BEST PTV, unique cold on-column inlets, and detector solutions for conventional GC and GC/MS applications. Its unique ability to provide in-series, staked or parallel configurations of up to three detectors featuring different selectivity, provide additional flexibility to lab operations. Dedicated turnkey analyzers for chemical and petrochemical applications complete the powerful TRACE GC Ultra product offering.

Ultra in system automation
Two new application notes illustrate how the proprietary direct column heating technology can decrease the total analysis time to levels unachievable with conventional fast GC analysis. The application notes discuss how the TRACE GC Ultra is able to perform simulated distillation of petroleum products and hydrocarbon index determination in environmental samples in less than two minutes.
High temperature programming, up to 20°C/s, and fast cooling times of approximately one minute, with precise retention time control are the key instrument features demonstrated in both application notes. The benefits delivered by this technology include a tremendous increase of sample throughput, with analyses performed twenty times faster than before, without compromises in precision.

Thermo GCs, including the versatile dual channel TRACE GC Ultra and the single-channel high productivity workhorse FOCUS GC, offer fast separation capabilities combined with the most innovative GC injection techniques.
