¡
Sample too viscous
too be drawn in with-
out air pockets
¡
Use the horizontal
operation mode and
dilute the sample, or
dose directly as a
solid.
¡
Inhomogeneous sam-
ple or sample con-
taining particles
¡
Homogenize sample
Low results
¡
Incomplete SO

for-
mation due to exces-
sive sulfur content
¡
Reduce sample size/
amount
¡
Dilute sample
¡
Metallic cations in
the sample lead to
sulfur salt formation
¡
Dilute samples, if
possible
Results too high
¡
Excessive halogen
and nitrogen con-
tents disrupt TS de-
termination
¡
Nitrogen: Use MPO
technology
¡
Dilute samples, if
possible
¡
Incomplete sample
incineration (pyroly-
sis products)
¡
Use a suitable com-
bustion mode or
