Features JMS-800D UltraFOCUS™ is an instrument focusing on ultramicro analysis, which is optimal for dioxins in HRGC/HRSIM mode, as well as the related compounds of PCB, PBDE, and POP compounds. Double Column GC Interface (Option) The UltraFOCUS™ has a double column 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 column 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. Detector The UltraFOCUS™ uses a 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.
