“A review of environmental microbiology
PT data sets documents that different EPA
approved methods tend to yield different
results for the same analyte,” according to Mark
Hammersla, President of NSI Lab Solutions. “We
feel that such commutability issues indicate that
a one-size fits all approach to microbiological
CRM preparation and certification could be
greatly improved upon. “What if, rather than
a plain vanilla non-selective certification of
CFU count, we expanded our CRM design
and certification protocol to include multiple
routine environmental methods? We could
include this data on the accompanying COA so
that our customers would be spared the hassle
of determining CRM performance for their
methods. We’d do it for them.”
Each microbiological CRM from NSI Lab
Solutions is now certified by multiple routine
environmental methods when applicable. All

Certified for multiple methods!
of this data is supplied on the product COA
making performance verification in your lab a
thing of the past. For example, suppose you
purchase our E.coli standard (Part# 9001H) as a
positive control for your coliform analysis. The
CRM is supplied with certification data for total
coliform, fecal coliform and E.coli by both MPN
and plate count methods. NSI Lab Solutions calls
this technique “establishing commutability so
you don’t have to.”
Don’t forget to check out our new multiorganism coliform CRMs for water and
wastewater analysis. Certified using 6 different
environmental methods, these are the only
multi-organism CRMs on the market.
