JEOL is a global leader in instrumentation for scientific research and industrial applications, providing innovative technologies and products for mass spectrometry, NMR and electron microscopy. Our AccuTOF GC-Alpha GC-MS system is the only high-resolution mass spectrometer that can combine GCxGC with high-resolution MS and a choice of EI, CI, PI and FI ion sources. The JEOL AccuTOF-DART MS is an Ambient Ionization Toolbox™ that introduced ambient ionization with the pioneering DART ion source and has since expanded to other ambient ionization technologies. Our TQ4000 GC-Triple Quadrupole MS/MS system provides unparalleled speed and accuracy for quantitative analysis of trace compounds such as pesticides, while the UltraQuad SQ-Zeta GC-Quadrupole MS is a routine benchtop GC-MS system with multiple ion sources (EI, CI, PI) and direct probe options. The JEOL SpiralTOF with MALDI Imaging produces high resolution mass spectra for the entire image, even for non-flat samples.
