About leak detection
Design
Great care has been taken with the design of the 3
rd
generation cell
in order to repeatedly obtain the same characteristics and to achieve
excellent stability:
- the metal parts are made of stainless steel,
- the filament holder is made of machined aluminium and filament
iridium,
- there is an integrated amplifier.
The cell assembly is composed of:
n The vacuum chamber:
The analyzer cell vacuum chamber is made of light alloy (aluminium).
n The main cover function is to contain and position the following 3
modules:
- ionisation module: "ions" generation,
- braking module: ions sorting and dispersed ions suppression,
- equipped plate module: recepted ions amplification.
n The preamplifier and its associated electronics:
- Power supply board: delivers power to all the components
- Measure board: Treat and convert the signal into a digital signal
(semi-log form).
- Preamp board: preamplification and mechanical interface.
