- Ion Source
EI electron impact source, with dual heating robs independent heating which makes heating more uniform. Max temperature is 350℃. Dual filament design provides double filament life. Electron energy 10-100eV adjustable, enabling low-voltage operation to meet application requirements. Tube-shaped lens enhance focusing effect and dramatically improve ionization efficiency. Patented surface repulsion electrode design dramatically improves ion focusing effect.
- Quadrupole Mass Analyzer
High precision metal molybdenum quadrupole mass analyzer, to achieve standard unit mass resolution. Removable pre-quadrupole filter device, to reduce pollution of main quadrupole and avoid cleaning maintenance. Pre-quadrupole equipped with scanning voltage with mass changes, to ameliorate fringing field, improve efficiency of ion incidence and achieve better detection sensitivity.
- Vacuum System
High performance pre-vacuum pump and turbo molecular pump, to reduce ion collisions, background noise and memory effect. Pre-vacuum using GLD-136 small direct oil rotary plate pump geometrical pumping speed 165L/min. Stage-vacuum using Germany PFEIFFEER innovate Hipac™ turbo-molecular pump with a more reliable design compact structure, higher pumping speed and more efficient cooling system. To suit your specific needs and budget, 2 specification are available.
- Vacuum Chamber
Cleaning is an essential maintenance process for an ion source, prequadrupole system. MS7250 supplies a side door design of the vacuum chamber, which makes cleaning much easier, routine maintenance much more simple.
