The ability to predict elemental formulae of each EI fragment is hugely powerful for metabolite identification.

– Karl Burgess

Powerful software for intelligent identificationThe Q Exactive GC system uses vast, readily available nominal mass electron ionization (EI) libraries (such as NIST and Wiley) to generate candidate compounds. Hits are verified using intelligent exact mass interpretation of the fragmented mass spectrum acquired. Customized HR/AM libraries can also be used

This technology will greatly facilitate the identification of unknown compounds.

– Joshua Coon

High confidence confirmationFor further information and/or confirmations of compounds, positive chemical ionization (PCI) can be used to yield molecular ions. These ions can be measured directly in the Orbitrap or after fragmentation in the HCD for further HR/AM investigation into the compound structure.

Analyzing whiskey and pesticide samples, to my

surprise, many compounds where automatically identified.

– Jana Hajšlová

d e t e c t

the ultimate screening toolPowerful, broad-scope sample screening and quantitation

Analyzing compounds present at low concentrations, quantitatively, with high selectivity using full scan acquisition has been out of reach for

GC-MS users for too long. Many leading laboratories in various fields require simultaneous targeted and untargeted sample screening, but

that need went unmet until now. Today, the Q Exactive GC system has the quantitative power of a GC triple quadrupole MS combined with

the high precision, full scan high resolution/accurate mass capability that only Orbitrap technology can offer. This combination will change

your workflows, forever.

Confident low-level detection and identification for high efficiency screening workflowsThe Q Exactive GC system offers routine operation, possible at 60k–120k resolution (at m/z 200) with sub-1 ppm mass accuracy and full scan sensitivity down to part-per-trillion concentrations. This capability drives truly powerful screening methods for food safety, environmental, anti-doping, and many other applications where ultra trace-level detection is required in difficult matrices.

For pesticides, I could safely see very low levels.

A step ahead in automated sampl ingA perfect match for the Q Exactive GC system, the Thermo Scientific™ TriPlus™ RSH autosampler utilizes robotic sample handling to expand automated capabilities beyond liquid, headspace, and solid-phase microextraction (SPME) injections to advanced sample handling cycles. Your results benefit from improved precision and reproducibility, while your laboratory gains unique advantages from the system’s unattended operations and sample handling flexibility.

• Automate basic sample and standards preparation procedures such as dilution, internal standard addition, and derivatization.

• High precison injection from low volumes to maximize your analysis opportunities with your most precious samples

• Automated toll exchange to switch between different syringes and techniques “on-the-fly”

Fast oven temperature cycling and excellent retention time performance mean that high-precison, high-productivity data sets can be realized. This type of data is especially important to facilitate statistics in larger batches, e.g., in “-omics”-type studies with many biological or technical replicates.

The TRACE 1300 Series GC quickly reaches near-ambient temperatures.

Outstanding retention time stability is achieved, even in the most complex GC and GC-MS applications, through the use of innovative and unique IEC (integrated electronic control) modules. This stability guarantees industry-leading 0.001 psi control through the entire working range. These miniaturized gas controls, integrated within every injector or detector module for compact, self-sufficient fully-featured devices, deliver strictly controlled pressure or flow to columns and detectors.Setting constant or ramped pressures and flows is easy through the software or the local user interface, while the electronic control maintains the stability during every run for exceptional retention time, accuracy, and precision. To further enhance analytical performance, the IEC module also supports the automated leak check of the injector and column installed and column evaluation procedures.

Retention time stability on 10 consecutive runs of hydrocarbon mix. Retention time standard

deviation is always ≤1/1000 minute.
