Microbiology Quality Control - Proficiency Testing

To test a performance or validate a microbiological method also typical samples should be used. RTC a Sigma-Aldrich Company produce therefore samples with defined organisms in a defined concentration and in a defined matrix. This certified reference materials (CRMs) is produced, certified and traceable in accordance with ISO Guide 34:2009 and ISO/IEC 17025:2005. Such samples build as well the base for proficency testing (or interlaboratory comparison).

WP = Water Pollution
WS = Water Supply

What are “3 Levels” Micros?
Three independent standards of three different concentrations to meet specific state requirements.

What are “4 Levels” Micros?
The 4 Level sets are designed to meet the Standards Council of Canada (SCC) proficiency testing requirements of testing 4 levels twice per year.

For single defined standard concentration for a specific organisms see also our portfolio of certified Vitroids.
