Front Cover: Quantitative Low‐Field 19F Nuclear Magnetic Resonance Analysis of Carbonyl Groups in Pyrolysis Oils

The Front Cover shows that low‐field, or benchtop, nuclear magnetic resonance (NMR) spectrometers can perform just as well as higher field spectrometers in the quantitative analysis of pyrolysis bio‐oils produced from a range of different feedstocks. Benchtop NMR spectrometers are typically smaller and less expensive than their superconducting counterparts and require neither cryogens nor specialist deuteriated solvents. Their wider use will make accurate NMR analysis of pyrolysis oils simpler, cheaper, and more accessible to a wide range of different users. More information can be found in the Research Article by B.
