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.
