PR:PROJECT_SUMMARY Methods: We used serum samples from a non-human primate (NHP), a baboon (Papio PR:PROJECT_SUMMARY hamadryas), with suitable quality controls to quantify the chemical space using PR:PROJECT_SUMMARY an advanced HR MS platform for confident metabolite identification and robust PR:PROJECT_SUMMARY quantification to assess the suitability of the platform for routine clinical PR:PROJECT_SUMMARY metabolomics research. In a comparative approach, we also analyzed the same PR:PROJECT_SUMMARY serum samples using a two-dimensional gas chromatography time-of-flight PR:PROJECT_SUMMARY mass-spectrometer (2D GC-ToF-MS) for metabolite identification and PR:PROJECT_SUMMARY quantification following established standard protocols. Results: Overall, the PR:PROJECT_SUMMARY 2D GC-ToF-MS and GC-Orbitrap-MS analyses enabled identification and PR:PROJECT_SUMMARY quantification of 555 total metabolites from the NHP serum with a spectral PR:PROJECT_SUMMARY similarity score Rsim ≥ 900 and S/R ratio of > 25. A common set of 30 PR:PROJECT_SUMMARY metabolites with HMDB and KEGG IDs were quantified in the serum samples by both PR:PROJECT_SUMMARY platforms where the 2D GC-ToF-MS enabled quantification of a total 384 PR:PROJECT_SUMMARY metabolites (118 HMDB IDs) and the GC-Orbitrap-MS analysis quantification of a PR:PROJECT_SUMMARY total 200 metabolites (47 HMDB IDs). Conclusions: Our study provides insights PR:PROJECT_SUMMARY into the benefits and limitations of the use of a higher mass accuracy PR:PROJECT_SUMMARY instrument for untargeted GC-MS-based metabolomics with multi-dimensional PR:PROJECT_SUMMARY chromatography in future studies addressing clinical conditions or exposome PR:PROJECT_SUMMARY studies.

For this study, we utilized a CO:COLLECTION_SUMMARY healthy adult male olive baboon (Papio hamadryas) maintained as part of the CO:COLLECTION_SUMMARY baboon colony at the Southwest National Primate Research Center, located on the CO:COLLECTION_SUMMARY campus of the Texas Biomedical Research Institute, San Antonio, Texas. The male CO:COLLECTION_SUMMARY baboon used in this study was 18 yrs. old. The baboon had been raised and CO:COLLECTION_SUMMARY maintained on a standard monkey chow diet (high complex carbohydrates; low fat) CO:COLLECTION_SUMMARY prior to the fasting blood collection. All procedures involving animals were CO:COLLECTION_SUMMARY reviewed and approved by the Texas Biomedical Research Institute’s CO:COLLECTION_SUMMARY Institutional Animal Care and Use Committee (IACUC). Freshly collected serum CO:COLLECTION_SUMMARY samples were stored in aliquots at -80 C until analysis.

The pooled extracts (~ 1500 µL) SP:SAMPLEPREP_SUMMARY from the two steps were dried under vacuum at 4 C prior to chemical SP:SAMPLEPREP_SUMMARY derivatization. Dummy extractions performed on blank tubes served as extraction SP:SAMPLEPREP_SUMMARY blanks to account for background (extraction) noise and other sources of SP:SAMPLEPREP_SUMMARY contamination. Six (S1, S2, S3, S6, S7, S8) samples were then sequentially SP:SAMPLEPREP_SUMMARY derivatized with methoxyamine hydrochloride (MeOX) and 1% TMCS in SP:SAMPLEPREP_SUMMARY N-methyl-N-trimethylsilyl-trifluoroacetamide (MSTFA) as described SP:SAMPLEPREP_SUMMARY elsewhere.23,24 Steps involved addition of 10 μL of MeOX (20 mg mL-1) in SP:SAMPLEPREP_SUMMARY pyridine incubated under shaking at 55 °C for 60 min followed by SP:SAMPLEPREP_SUMMARY trimethylsilylation at 60 °C for 60 min after adding 90 μL MSTFA.

Injection temperature was set at 250 °C (front inlet) and the helium CH:CHROMATOGRAPHY_SUMMARY (carrier gas) flow rate was set to 1 mL min-1. Separation on the GC was achieved CH:CHROMATOGRAPHY_SUMMARY using two columns, a primary Rxi®-5Sil MS capillary column (Cat. No. CH:CHROMATOGRAPHY_SUMMARY 13623-6850, Restek, Bellefonte, PA, USA) (30 m × 0.25 mm × 0.25 μm) in line CH:CHROMATOGRAPHY_SUMMARY with a secondary Rxi®-17Sil capillary column (Cat. No. 40201-6850, Restek, CH:CHROMATOGRAPHY_SUMMARY Bellefonte, PA, USA) (2 m × 0.15 mm × 0.15 μm). The temperature program for CH:CHROMATOGRAPHY_SUMMARY the primary column started isothermal at 70 °C for 1 min followed by a 6 °C CH:CHROMATOGRAPHY_SUMMARY min-1 ramp to 310 °C and a final 11 min hold at 310 °C. The secondary oven CH:CHROMATOGRAPHY_SUMMARY temperature was programmed with an offset of 5°C whereas the modulator CH:CHROMATOGRAPHY_SUMMARY temperature offset was 15° C relative to the first oven temperature. The CH:CHROMATOGRAPHY_SUMMARY modulation temperature (second-dimension separation time) was 4 s divided into a CH:CHROMATOGRAPHY_SUMMARY hot and cold pulse times of 0.60 s and 1.4 s, respectively between the two CH:CHROMATOGRAPHY_SUMMARY stages.
