Wastewater Demands
CRMs for Demands Analysis
GGA SnipsTM were designed to help reduce the
incidence of a non-conforming GGA test in the
wastewater lab. Several potential issues with a
GGA standard can contribute to the incidence of
GGA non-conformance. The design and use of
our GGA snip prevents these issues:
• GGA SnipsTM are always formulated from
certified highest purity chemicals using
a validated standardized procedure. This
prevents problems that may result from
lot to lot variance due to inadequately
controlled raw materials.
• GGA SnipsTM are packaged for single use
preventing inadvertent cross-contamination
in your lab.
• GGA SnipsTM are analytically certified
for formulation accuracy against a NIST
SRM assuring you not just of the solution
accuracy, but also providing you a valuable
link to SI.
• And finally, GGA SnipsTM are sterilized in the
tube after packaging. This prevents unrecognized microbial degradation making
the GGA snip stable for more than 3 years
when stored at room temperature.
• GGA SnipsTM are filled to deliver the
required volume of standard to an
accuracy of 0.5%. This prevents GGA nonconformances due to inaccurate pipetting.
We hope you give our CRMs for demands a try.
