MStation™ Double-Focusing Magnetic Sector Mass Spectrometer

JMS-700 MStation™

JMS-700 MStation™ Double-Focusing Magnetic Sector Mass Spectrometer

The JMS-700 MStation™ is a fully-automated, high-performance, double-focusing magnetic sector mass spectrometer designed for high-resolution GC/MS analyses. The MStation is capable of achieving a resolving power of 60,000 or greater at 10% valley.

The elegant ion optics design permits rapid and reliable auto-tuning with minimal operator intervention, even under high-resolution conditions. EI and CI capability come standard. Optionally available ion sources and attachments include: FAB, Frit-FAB and High-Energy CID. The MStation™ supports a wide range of analytical applications.

JMS-800D UltraFOCUS™

JMS-800D UltraFOCUS™ Double-Focusing Magnetic Sector Mass Spectrometer

The JMS-800D UltraFOCUS™ is the ultimate choice for ultra low-level trace detection applications, such as monitoring for dioxins and related compounds e.g. Polychlorinated Biphenyls (PCBs), Polybrominated Diphenyl Ethers (PBDEs)or drugs of abuse, by high resolution-selected ion monitoring (HRSM) gas chromatography/mass spectrometry (GC/MS).

Key Features

JMS-800D UltraFOCUS™

Double Column GC Interface (option)

The UltraFOCUS has a double columnc GC interface to allow the simultaneous connection of two GC injectors with separate GC columns. The pumping configuration and capacity allows change of the GC columns without venting the instrument, reducing instrument downtime and increasing productivity. The unique double column GC interface enables direct line of sight GC column setting into the source region, as well as giving an improved thermal variation profile.

Ion Chamber

The socket Electron Ionization (EI) chamber allows rapid and convenient change of ion chamber without venting the instrument.

Premier Magnet

The magnet is made of fully laminated rolled grain-oriented steel with high permeability and low hysteresis. The magnet design features an extra-wide gap and so allows use of a wider flight tube, giving higher transmission and reducing any susceptibility to contamination.


The UltraFOCUS uses as 20kV conversion dynode photomultiplier with 'point detecting' technology, which ensures both stable longevity of the instrument and sensitivity enhancement on compounds with m/z >500.
