54 AIR POLLUTION INSTRUMENTATION
In each of the above cases, instrumentation is selected based
on the requirements and the length of the program. Monitors
are available for all parameters for which the National Ambient
Air Quality Standards (NAAQS) have been set.- Suspended Particulates
- Sulfur Dioxide
- Oxides of Nitrogen (as NO 2 )
- Total Hydrocarbons (Non Methane)
- Photochemical Oxidants
- Carbon Monoxide
In each case, an EPA reference test method has been estab-
lished and to monitor for any of the above, an instrument
employing that approved reference method must be utilized.
If a parameter is chosen and no reference method is avail-
able, then direct contact with the EPA or the governing regu-
latory body is highly recommended before proceeding with
the monitoring program.
The identification of continuous Reference or Equivalent
Methods for NAAQS parameters can be obtained by writ-
ing the Environmental Monitoring and Support Laboratory,
Department E, US Environmental Protection Agency,
Research Triangle Park, NC 27711.
In addition to the NAAQS parameters, selected meteoro-
logical data will also be required for the analysis and unless
the proposed test site is near a National Climatic Recording
Station, a meteorological recording station must also be
established to collect at a minimum, wind speed and direc-
tion, humidity, and temperature. This can be accomplished
through the use of a highly portable compact system or very
sophisticated meteorological monitoring system employing
such items as a 30 meter tower with monitors at different
heights, daily weather balloon releases, etc.

Air quality monitoring instrumentaion includes a chemilumi-
nescence O 3 analyzer, a fluorescence SO 2 analyzer, an infra-
red CO analyzer, and an NO 2 analyzer. These four instruments
have received reference or equivalent method designation from
the EPA. Each instrument is a totally self-contained system that
offers precise interference-free measurement, convenient inter-
face with peripherals, minimum expendables for ease of main-
tenance and choice of mounting options. Beckman Instruments

Byron Instruments Air quality instruments analyze
hydrocarbons, organics, methane, carbon monoxide and
carbon dioxide at source and ambient levels. The total emission
analyzer oxidation/reduction system insures accurate read-
ings. The analyzer gives part-per-million carbon readings on
non-methane hydrocarbons from 10 ppmc full scale to 50,000
ppmc (5%) full scale. The instrument also provides readings
on total hydrocarbons, methane, carbon monoxide, and carbon
dioxide each analytical cycle. Byron Instruments Inc., 520-1/2
