SOURCE + TRANSFER
PI-Purify
Generate and transport ions into vacuum for downstream experiments and instrumentation.
CONTROLLED ION-BEAM TECHNOLOGY
Soft landing meets mass spectrometry.
pureions develops modular systems for generating, transferring, mass-selecting and depositing complex molecular ions with precision.
THE ION PATH
Control every step between source and surface.
Controlled Ion-Beam Deposition brings the selectivity of mass spectrometry into surface preparation. The platform is organized around a clear sequence of functions, each supported by dedicated hardware and control electronics.
- 01
Generate
Bring complex molecules into the gas phase through electrospray or another suitable ion source.
- 02
Transfer
Guide ions from atmosphere into vacuum through efficient, differentially pumped stages.
- 03
Select
Analyze and filter the ion beam with a digital quadrupole mass filter.
- 04
Land
Deliver a defined dose to a target with controlled kinetic energy.
SYSTEMS + COMPONENTS
Start with the part of the ion path you need.
Use a complete chain or integrate selected functions into an existing experimental setup.
MASS SELECTION
PI-Quad
Add flexible digital quadrupole mass filtering, electronics and software to an ion path.
COMPLETE CHAIN
PI-Select
Combine ion generation, transfer and mass selection in one integrated platform.
WHY PUREIONS
Built to make the ion beam measurable and adaptable.
The platform combines ion optics, vacuum hardware, local signal generation, rack electronics and software. Its modular architecture keeps interfaces clear and supports future extensions.
