NSI 2014 Digital Catalog | Page 2

Table of Contents 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.

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.
