Microbiology Microbiology CRMs For Wastewater and Drinking Water Microbiology Product Listings Except where noted, standards are formulated at 1000-2000 CFU. Actual certified values are listed on an accompanying COA. Single Organisms “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.

Actual certified values are listed on an accompanying COA. 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.
