Gas is ionized, ions are accelerated, and then they fly through a vacuum path to the detector. Light ions arrive first, heavy ions arrive later. The arrival time becomes a mass spectrum.
A hot emitter sends electrons into the ionization region. There they hit gas molecules and turn them into positively charged ions, each gas with its own mass.
An electric field pulls the ions into the flight path. Because they start with the same energy but have different masses, their velocities differ: light ions are fast, heavy ions are slow.
In the field-free region, ions travel at constant velocity. H₂O · 18 arrives first, then N₂ · 28, and finally HC · 78+. Every arrival time becomes a peak in the spectrum.
With our patent-pending TOFX technology, we achieve high sensitivity and strong mass resolution in a very compact space.
TOF300 combines total pressure measurement with a compact gas analysis architecture. Instead of providing only summed information about the process, the system creates a directly usable picture of relevant gas components, robust enough for real environments and clear enough for quick decisions.
Pressure changes and gas composition are acquired continuously.
Signatures such as water, air, helium, or hydrocarbons become interpretable.
Causes become visible earlier and corrective actions can be derived more precisely.
