Summary Only in very recent times, desktop NMR spectrometers have become available as tools for research and education. We have investigated in how far 1 H and 13 C NMR spectra acquired at 1 T with a compact NMR spectrometer are suitable for quality control of solutions from raw rubber in the rubber manufacturing industry. NMR spectra of samples drawn from oil‐extended styrene‐butadiene rubber (SBR), solution polymerized SBR, emulsion polymerized SBR, and SBR from different lots and the same lots are reported. Differences are observed not only between SBR samples polymerized in different ways but also between the same type of SBR from the same and from different lots from the same manufacturer.
