Voltage%.
Current calibration not
correct for sample (off by
a factor of 2 or 3)
Use correct calibration for
sample.
Sample concentration too
high
Prepare sample/matrix
with a final sample
concentration appropriate
for sample and matrix.
See “Matrix Information”
on page 3-6.
Excess matrix in sample
preparation
Increase sample:matrix
ratio.
Too much salt or buffer in
sample
Clean up sample. See
Section 3.1.5, Sample
Cleanup.
On Voyager-DE PRO and
Voyager-DE STR
systems, not separating
isotopic peaks in reflector
mode up to mass 1,000
Adjust Accelerating
Voltage to 10,000 V and
reacquire spectrum. See
Section 5.4.4.2, Setting
Accelerating Voltage.
