The ESR devices of the JEOL X3 series display exceptional performance. They combine the greatest degree of sensitivity with fully automated standard operations and an intuitive user interface. The generous expansion capacities of this series with many other hardware components displays an unmatched level of flexibility. With it new X3-series systems, JEOL offers a high standard in the field of ESR spectroscopy.
Organic basic chemicals are an elemental component of the manufacturing chemical industry. Precise molecular characterisation is essential for any further processing. Thanks to their diversity, the high-performance JEOL spectrometers are capable of quickly and efficiently resolving all structural questions.
