CRMs for Solids Analysis
Use of ISO Guide 34 certified reference materials
to QA your routine solids analyses has never
made more sense. Our CRMs for solids are
simply a good value:
• All of our solids CRMs are easy to
implement and use. There is no preparative
step, simply shake the bottle well and
measure the appropriate aliquot.

• The value assignments for all of our CRMs
are directly traceable to NIST through mass
calibrations providing you a direct link to SI
for all of your analyses.
• Each of our solids CRMs is verified to
work with the methods you use everyday,
because we verify each lot’s performance
with routine environmental methods.

• The results generated with our solids
CRMs are reproducible lot to lot, because
we’ve standardized and validated our
manufacturing process to the smallest detail
including raw material grain size.
