Introduction
Slurry is the name used
to define a suspension of
particles in a liquid. When a
sample is not easily rendered
into a liquid state, slurry
analysis may be a reasonable
alternative. Examples of
these types of samples are
refractory ceramics, coal,
slags, rocks, and silicon
carbide. The sample must be
finely ground into consistently
sized particles and suspended
in an appropriate liquid.
An example of a commonly
analyzed slurry is used
engine oil which contains
a suspension of small
metal particles resulting
from the wear of the
engine components. If the
particle size and density are
optimized, the slurry can be
routinely aspirated into an
ICP-OES or ICP-MS and
its metal content accurately
determined. An excellent
review by Ebdon et al,1
provides a thorough review
of this topic.
A number of atomic and mass
spectrometric techniques
have been used for slurry
analysis, including those listed
in Table 1.
To determine the relative
usage of these techniques,
we searched the archives
of the Journal of Analytical
