“…The experiments were carried out at the Atomic & Molecular Physics Beam Line (BL09U) at the National Synchrotron Radiation Laboratory in Hefei, using synchrotron radiation from an 800 MeV electron storage ring and a beam current of 400 mA. The beamline and experimental apparatus have been described in detail elsewhere 35–38 . The energy range of the VUV light is 7.0–124.0 eV.…”

Rationale Biomass is a potential feedstock for making liquid fuels and valuable chemicals. Quantitative analysis of biomass conversion in real time by photoionization mass spectrometry (PIMS) is an important way to understand the reaction process. However, the lack of photoionization data for biomass‐derived compounds limits the research using PIMS. Methods Measurements of photoionization data were performed with synchrotron vacuum ultraviolet PIMS. Toluene and methanol were used as calibrated references and solvents in this experiment since their photoionization cross‐sections (PICS) are well documented in the literature. Results The ionization energies (IEs) of 23 biomass‐derived compounds were measured. Among them, the PICSs of 14 compounds were calibrated and presented. Besides, the IEs of 95 other biomass‐derived compounds and their typical fragment ions were also summarized. Conclusions A photoionization database related to IEs and PICSs of biomass‐derived compounds (m/z < 200) is established. PICSs of most biomass‐derived compounds have low values at the most frequently used photoionization energy of 10.5 eV. Lignin‐derived compounds have lower IEs than carbohydrate‐derived compounds.
