Tuning for Sensitivity (Agilent 7500a)

Tune the Agilent 7500 for sensitivity to ensure that the instrument produces the best
results for the masses being analyzed. Achieve good sensitivity by running a
recommended tuning solution of 10 parts per billion (ppb) of Li, Y, Ce and Tl.
If you are using the Agilent 7500ce, refer to "Tuning for Sensitivity (Agilent
7500ce)" on page 4-39.
If you are using the Agilent 7500cs, refer to "Tuning for Sensitivity (Agilent
7500cs)" on page 4-62.
N O T E When an internal standard solution is added to a sample by the peristaltic pump and
the internal standard solution overlaps tuning elements, it might cause wrong tuning
parameters. To avoid this situation, the sample tube for the internal standard solution
must be placed in pure water while tuning.
To tune for sensitivity, complete the following steps:
>>
1 Select Instrument Tune in the ICP-MS Top window.
The ICP-MS Tuning-Sensitivity window for sensitivity appears.
