With more than 50 years of Mass Spectrometry and NMR experience -- and innovations such as revolutionary DART technology for open air, exact mass analysis -- JEOL provides a wide range of instruments for investigating chemical and molecular compositions and structures.

JEOL analytical instruments serve a variety of needs in the biomedical, pharmaceutical, chemical, environmental, and homeland security fields, helping researchers to identify chemical compositions and molecular structure.

Direct Analysis in Real Time (DART™) mass spectrometry enables simple, immediate detection of exact masses in open air, without sample alteration. JEOL Time-of-Flight (TOF), liquid chromatograph (LC), and gas chromatograph (GC) mass spectrometers precisely identify chemical compositions and detect trace contaminants in minute samples.

JEOL nuclear magnetic resonance (NMR) spectrometers – with maximum field strengths from 300-920 MHz – characterize proteins and enable molecular identification using a single application platform – DELTA™ - which unifies data acquisition and output.
