dear
friends...
Thank you for checking out our new catalog
of reference materials and certified reference
materials (CRMs) for water and wastewater
testing. As you go through this catalog, I
think you will come to see that here at NSI
Lab Solutions we try to do things differently.
We believe that reference materials should
not only serve as a traceable link to SI for all
of your testing, but also should simplify and
reduce the cost of your operation. For each
testing category detailed, you will see unique
approaches to design and certification that
meet our philosophy.
• Maybe your interest is in coliform testing.
On pages 1-2 we detail our unique approach
to certification of microbiological CRMs
using multiple routine analytical methods
to establish method specific performance
criteria.

• Don’t miss our total and free chlorine
reference materials packaged in single use
Teflon® Snips™. They require no pipets or
cumbersome dilution schemes to prepare
and are detailed on pages 3-4.
• We designed our Universal Wastewater
Standards, detailed on page 9, specifically
to simplify reference material management
in the small wastewater laboratory. A unique
design allows you to QA up to 14 analytes
from a single bottle.
Again, thank you for checking out our new
catalog. Please don’t hesitate to contact me
with any questions.
