1-A.
Use this option to search the database for an analyte name.
1-B. If you know the exact spelling of an analyte, enter it here
to quickly retrieve, compare, and contrast a list of methods
in NEMI.
Note: Spelling must be exact for option #1-B to
work. If you do not know the exact spelling, use either Option #1-A above
or click on the "Advanced Search" tab which allows you to
scroll through the analyte names.
Quick search: Three choices: (1) Search
by analyte name;
(2) search by CAS number; and (3) search by method number from a dropdown
list.
Advanced search: presents more options, including a drop-down
list from which to select analyte name, as well as the ability to
limit methods returned based on detection level, method source, and
the analytical instrumentation used.
General search: Look for methods under general categories,
including media (air, water, soil, etc.), subcategory (organic, radiochemical,
etc.), source (EPA, USGS, etc.), or instrumentation.
Regulatory search: Need a method approved for drinking water
or wastewater regulations? Start here.
The Browse Methods page presents several other ways of accessing
data in the NEMI database.
2. Search
by analyte CAS* number
Search using analyte code (*usually the CAS number for chemicals; may
be an identifier from another system in some cases. Need to include dashes
in CAS number; i.e., 14797-55-8).
3. Search
by method number
Search
by method number
If you already know the number of the method you are interested in, you
can use this query to provide a listing of analyte performance data for
the method.
