The family 125 uses the QME 125 mass filter electronics with the mass ranges 100
and 200 amu and QMA 125 analyzers with 6 mm rod diameter.

QMI 422
With QMS 422 rather than QMI 422 the system bus and consequently the options
are also available for this family.
The basic unit comprises the power supply,
QC 422 quadrupole controller and the system
bus.
For family 400 components the IS 420 and
HV 420 or HV 421 are installed.
Input/output modules can be installed in
either family.
The QMI 422 comprises the power supply
and QC 422 quadrupole controller and allows
computer operation of family 125 equipment.
QMH/QMA 400 can be operated, but without
ion source and SEM supply.
The only option available is the AO 421
analog output or IC 421 ion counter.
The EP 422 amplifies the very small ion current signals of
the analyzer to voltage levels that are suitable for further
processing. It is installed directly on the analyzers in order
to minimize parasitic noise.
•
Compact, simple installation on QMA
•
Low-noise, low-drift, little vibration sensitivity
•
Fast response and quick recovery form overdriving
400
On analyzers with 90°off-axis SEM, two EP 422 can be connected. This
allows simple changeover from Faraday to SEM mode.
