XRF Analysis of Carbonblack
CSFR, January 1991
327 mg of loose powder on supporting film,
slightly pressed to ensure that top surface // bottom surface.
Rh tube, Helium. Results are in [Mass %].
99.29 Rest found by UniQuant
set to Case = 2
No customer's standards were used for calibration. A customer's
measured and treated as an unknown sample. The specified standard
were not given to us. However, the customer was baffled by the
results above and
the first reaction was:
"It seems as if UniQuant
has been especially developed for the analysis of carbonblack".
80 % of the lab’ s samples are carbonblack which before were
other (very time consuming) methods. Now all carbonblack samples
are routinely analyzed
by the PW1480 + UniQuant.
