2 Thermo Scientific irm-gc/ms Get more Information from your GC Samples... The Thermo Scientific irm-gc/ms is the first fully integrated irm-gc/ms system which is operated like a GC/MS. The new Thermo Scientific GC IsoLink unit integrates the Thermo Scientific TRACE GC Ultra gas chromatograph with the Thermo Scientific DELTA V isotope ratio mass spectrometer into one easy-to-use unit. The isotope ratios of all compounds in a GC application can now be monitored with precision of better than 2 ppm ( at%). The GC IsoLink unit incorporates the knowledge and experience of an installed base of more than 800 irm-gc/ms systems. All injection techniques and detector systems including Thermo Scientific GC/MS analyzers can be an integrated part of the irm-gc/ms system creating the most powerful analytical tool set.

3 Structural Elucidation by GC/MS Separation by High Resolution GC 13 C / 12 C Isotopic Fingerprints by irm-gc/ms...by adding irm-gc/ms Isotope ratio monitoring-gc/ms Chemical and physical processes can change the natural isotope composition of organic compounds. The carbon, nitrogen, oxygen and hydrogen isotope ratios preserve a trace to these events in every molecule of a compound. These isotope signatures reveal information not accessible in any other way. This includes the origin of a compound, its synthesis pathway, conditions at its formation, sometimes even a substrate can be discovered. Paleoclimatic and diagenetic conditions can be resolved by the compound specific isotope analysis of biomarkers. Metabolic pathways can be unraveled by using isotopic tracers with lowest artificial isotope enrichment or with a distinctly different natural abundance. While GC/MS provides information on structural elucidation and compound quantitation, isotope ratio monitoring GC/MS (irm-gc/ms) reveals the history and origin of compounds by reading their isotopic signature with ultrahigh precision. Small variations of the natural isotope abundances cannot be detected with GC/MS systems. Only the combination of a GC and an isotope ratio mass spectrometer is capable of routinely achieving the required precision. This combination allows to determine the isotope ratios of all individual compounds in a complex mixture. All fields of application using GC and GC/MS can benefit from isotope ratio monitoring GC/MS. Isotopic fingerprints analyzed by irm-gc/ms may still provide information where classical GC/MS methods based on compound quantitation cannot. 3

Compound specific isotope analysis of 13 C, 15 N, 18 O, and 2 H All GC-volatile compounds Analysis in the picomole range One automated sequence for 13 C, 15 N and 2 H determination High GC performance due to true capillary design Fully automated and maintenance-free operation Self-diagnosis and determination of system parameters Combination of quadrupole MS with irm-gc/ms TriPlus autosampler, ConFlo IV universal interface, GC IsoLink unit and Trace GC Ultra gas chromatograph. Doping Control: Prolong Detection of Testosterone Administration Analysis and Confirmation of Synthetic Testosterone Synthetic testosterone has a different isotope ratio than natural, endogenous testosterone. Therefore doping can be detected by comparing an athlete s testosterone isotope ratio with the isotope ratio of its endogenous precursors, e.g. cholesterol. This is much more sensitive and specific than monitoring compound ratios such as the testosterone/epitestosterone ratio. *Data courtesy of German Sports University Cologne, Germany, Center for Preventive Doping Research/Institute of Biochemistry.

5 GC/MS analyzes the ionized molecule and its fragments for quantitation and structural elucidation. irm-gc/ms enhances all isotope information by converting the compounds into simple gases, such as CO 2, N 2, H 2 or CO. The new GC IsoLink unit eliminates the complexity of this conversion and for the first time allows automatic switching between elements, controlling all aspects of the conversion....by adding irm-gc/ms Ecology and Metabolic Studies: Explore Complex Ecosystems Elucidation of Metabolic Pathways The isotope ratios of substrates, metabolites, and biomarkers are used to explore complex ecosystems with respect to structures of food chains, sources of compounds, detection of species involved in specific processes. Artificially and naturally labeled compounds in combination with irm-gc/ms analysis enable direct identification of species, elucidation of pathways and turnover rates. These concepts do apply to all biological applications with the focus on dietary and life conditions, migration patterns, position in food webs, metabolic processes and diseases.

6 Thermo Scientific irm-gc/ms Principle of irm-gc/ms The separation power of capillary GC is now combined with the high precision of Isotope Ratio MS using the new GC IsoLink unit for compound specific isotope analysis of 13 C/ 12 C, 15 N/ 14 N, 18 O/ 16 O and D/H. Each organic compound eluting from the GC column is converted into simple gases when traversing one of the capillary microreactors. Two conversion techniques are applied: Quantitative high temperature combustion for 13 C and 15 N determination converts compounds into CO 2, N 2 and H 2 O at up to 1450 C. The H 2 O formed in the oxidation process is removed on-line and maintenance-free. Injector Oxidation 1100 C Quantitative high temperature pyrolysis for D/H and 18 O/ 16 O determination converts organic H to H 2 at 1450 C and organic O to CO at 1280 C in inert and reductive capillary reactors. Because quantitative conversion is achieved no additional clean up is required. Fully automated computer control directs the GC flow into the combustion or the pyrolysis reactor which allows for the first time the analysis of 13 C, 15 N and 2 H within one batch of sequences. This new feature makes irm-gc/ms as easy to operate as classical GC/MS systems.

The molecular fingerprint of such products changes when exposed to the environment due to physical and chemical processes, losing the link to original sources. In contrast, the isotopic fingerprint of oils does not alter during environmental degradation.

7 Thermo Scientific Isodat Software Suite for irm-gc/ms The irm-gc/ms system is fully automated and controlled by the Isodat software suite. This program is focused on continuous routine analyses with a fast setup of all methods and sequences. When coupled to a GC autosampler, the system can be operated fully unattended for high sample throughput and high productivity. All GC injection techniques and additional GC detectors are fully supported. The irm-gc/ms does not require any user interaction during operation. Automated system parameter control, data evaluation and report generation make irm-gc/ms as easy-to-use as standard GC/MS. The Thermo Scientific irm-gc/ms technology can also be hyphenated with the Thermo Scientific DSQ II single quadrupole GC/MS for simultaneous isotope and structural elucidation using the Isodat software suite and Thermo Scientific Xcalibur data system software.

Oils derived from source rocks still retain a strong signature of the hydrogen isotopic compositions of source organic matter and source water. This indicates that 13 C/ 12 C and D/H values can be used for oil-source correlation and for paleoenvironmental reconstructions. 2 [V] 3/ C pristane D/H Ratio Trace H 2 Trace C phytane Time (s) δ 2 H [ ] of alkanes with GC separation of C 17 / pristane and C 18 / phytane. 7
