JEOL is now able to look back on 60 years of experience in the field of NMR complete systems - no other manufacturer is able to claim this. JEOL instruments have always counted among the quickest, most stable, most reliable and most robust devices on the market. Room temperature or cryogenic sample heads, high-resolution solid NMR spectroscopy or liquid NMR spectroscopy for routine examinations - JEOL offers a tailor-made solution for every application. And all of this outstanding JEOL technology is rounded off with an exceptional, award-winning design.
Inorganic base materials form the basis of a number of important industrial intermediate and end products (e.g. plastics, dyes, fertilisers). These basic materials therefore already have to fulfil certain quality criteria. The powerful systems from JEOL enable the structural characterisation of such chemicals and thus make unequivocal statements regarding their composition and purity.

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.
