6.1 Instrument Automated Setup
The ASpect MS can automatically perform plasma alignment, resolution and trim and
mass calibration routines.
All routines use the same default System Setup-worksheet: System Setup.msws. They
require the 1 µg/L (1 ppb) tuning solution.
Some customers use the instrument automated setup as a daily start-up of the
PlasmaQuant MS because you can add to the routine that the plasma is automatically
ignited and the system is warmed up.
1. Click the arrow next to the I
NSTRUMENT icon on the Main Toolbar and select

can close the I
NSTRUMENT AUTOMATED SETUP window.
6.2 Torch alignment
It is important to ensure that the torch axis is perfectly aligned on the axis of the
sampler cone orifice for optimal signal efficiency. This should be done every time a
torch is installed or disturbed (e.g., moved aside to change/clean the cones).
It is a common practice to do this following routine once a week. It only takes about
five minutes to complete.
When done automatically, the best XY position found is stored by the instrument until
the next adjustment. The peak is found by summing all of the enabled isotopes
together and then selecting the location of the maximum of this signal. This means
that sometimes the selected peak may not be coincident with the maxima of the
largest signal scan present.
