Mass (axis) offset
Mass offset (MassOffs) also controls the mass assignment.
•
A higher offset yields higher mass assignment.
•
Mass offset generally affects peaks equally at all masses.
Quadrupole maintenance
The mass filter requires no periodic maintenance. It should not
be removed from the radiator. If
absolutely
necessary (that is, if
the only alternative is replacement), the quadrupole can be
cleaned. Cleaning
must
be performed by Agilent Technologies
service personnel.
C A U T I O N
Never put the quadrupole in an ultrasonic cleaner.
Never change the physical orientation of the quadrupole mass filter.
The fused-quartz quadrupole is fragile and will break if dropped or
handled roughly.
The material in the cusps of the quadrupole is very hygroscopic. If
exposed to water, the quadrupole must be dried very slowly to
prevent damage.
