Stable isotopic compositions of volatile organic compound reference materials USGS96-105 measured at the U.S. Geological Survey Reston Stable Isotope Laboratory (RSIL), 2024–2025

Ten volatile organic compound matrix reference materials (RMs) were analyzed for hydrogen, carbon, nitrogen, oxygen, and sulfur stable isotopic compositions at the Reston Stable Isotope Laboratory (RSIL) of the U.S. Geological Survey from 2024-2025. The RMs are acetonitrile, benzaldehyde, bis(methylthio)methane, dimethylsulfide, ethyl 2-methylbutyrate, furfural, 2-methyl-1-butanol, 1-octen-3-ol, (1S)-(-)-β-pinene, and toluene. Data includes raw and normalized isotopic data. Samples were normalized using two-point normalization using international reference materials. This dataset represents the RSIL contribution to a larger inter‑laboratory calibration of the reference materials.
