Introduction
The NECi Nitrate Reductase
Nitrate Analysis Method is in the process of being "Certified" by US
Geological Survey (USGS) and other agencies.
Proposals for "Certification"
- A proposal to "Standard Methods for the Examination
of Water and Wastewater" (http://www.standardmethods.org/)
for a new nitrate analysis method has been submitted by NECi and its
status is pending.
NECi "Standard Methods" Proposal:
-
New
method for Method 4500-NO3- NITROGEN
(NITRATE)
-
Proposed title:
Enzymatic Reduction Method
-
Based on:
Campbell,
Wilbur H., P Song, GG Barbier (2006) Nitrate Reductase for Nitrate Analysis
in Water. Environmental Chemistry Letters, 4: 69-73.

A 2nd
"Standard Methods" Proposal has been submitted for:
-
New
method for Method 4500-NO3- NITROGEN
(NITRATE)
-
Proposed title:
Automated Enzymatic Reduction Air-segmented Continuous Flow
Analysis Method (PROPOSED)
-
Based on:
Patton CJ, AE Fischer, WH Campbell & ER
Campbell (2002) Corn leaf nitrate reductase: A nontoxic alternative to
cadmium for photometric nitrate determinations in water samples by
air-segmented continuous-flow analysis. Environmental Science and
Technology, 36: 729-35 Read this

An application to
the US Environmental Protection Agency (EPA) is in preparation. In
this case, the NECi NaR Nitrate Analysis Method will be proposed in the
EPA Alternative Test Procedures (ATP) Program.
See:

NECi "EPA ATP"
Proposal:
-
NITROGEN, NITRATE-NITRITE
-
Method 353.X (Colorimetric, Automated, Enzymatic Reduction)
Nitrate Analysis Not Requiring "Certification"
Many types of
samples do not require that the nitrate analysis method be "Certified".
For all these types of samples, the NECi NaR
Nitrate Analysis Method can be used.
