Precision Charge Neutralisation
Just enough gas, exactly where it's needed.
A trace of gas, delivered to the ROI.
A motorised needle carries the jet there and keeps it there. Neutralising the charge takes a very small flow — nothing like backfilling the whole chamber.
Built for the katana
A dedicated attachment for the katana microtome — it slots into the hardware and software you already run.
Non-conductive samples, without the charge
The same resin-embedded block face, without and with Precision Charge Neutralisation — both imaged at high vacuum.
