Are you interested in finding out about Air Quality?
Do you have questions in relation to Air Quality?
Look no further.
There is a lot of information, about Air Quality, and how we handles
Air Quality.
Air Quality
4
Air pollution
Air pollution comes from many different sources: stationary sources such
as factories, power plants, and smelters and smaller sources such as dry
cleaners and degreasing operations; mobile sources such as cars, buses,
planes, trucks, and trains; and naturally occurring sources such as
windblown dust all contribute to air pollution.
Air Quality can be affected in many ways by the pollution emitted from
these sources. These pollution sources can also emit a wide variety of
pollutants.
The EPA has these pollutants classified as the six principal
pollutants (or criteria pollutants-as they are also known). These pollutants
are monitored by the EPA, as well as national, state and local
organizations.
Air Quality
5
Finding out if the Air we Breathe is Clean
The six criteria pollutants addressed in the NAAQS are Carbon
Monoxide, Nitrogen Dioxide, Lead, Ozone (or smog), Particulate
Matter, and Sulfur Dioxide.
If the levels of these pollutants are higher than what is considered
acceptable by EPA, then the area in which the level is too high is
called a no attainment area.
The Air Pollution Monitoring program monitors all of the six criteria pollutants.
Measurements are taken to assess areas where there may be a problem, and
to monitor areas that already have problems. The goal of this program is to
control areas where problems exist and to try to keep other areas from
becoming problem air pollution areas.

NAAQS - US EPA
The Clean Air Act, which was last amended in 1990, requires EPA
to set National Ambient Air Quality Standards for pollutants
considered harmful to public health and the environment.
The Clean Air Act established two types of national air quality
standards.
• Primary standards set limits to protect public health, including the health of
"sensitive" populations such as asthmatics, children, and the elderly.
• Secondary standards set limits to protect public welfare, including protection
against decreased visibility, damage to animals, crops, vegetation, and
buildings.

… NAAQS - US EPA
The EPA Office of Air Quality Planning and Standards
(OAQPS) has set National Ambient Air Quality Standards for
six principal pollutants, which are called "criteria" pollutants:
PM10 & PM2.5, SO2, NO2, CO, O3, Lead
Units of measure for the standards are parts per million (ppm)
by volume, milligrams per cubic meter of air (mg/m3 ), and
micrograms per cubic meter of air (µg/m3 )

International standards and guidelines (WHO-US EPA)

SO2 Analysers

“ Fluorescence “
- emission of light or Luminance from electronically excited state of a molecule
Sulphur dioxide absorbs light in three primary UV regions.
Out of these, the band between 190 nm and 230 nm is best suited for
fluorescence measurements.
Absorption of ultraviolet radiation by SO2 molecule yields an excited
Molecule SO2*. SO2* then releases its excess energy by fluorescence
at a different wavelength, typically between 240 - 420 nm
Measurement Principle

Measurement Principle
40
The sample gas flows through a "Kicker" which removes hydrocarbons from
the gas stream through a selective permeation membrane.
The excitation light is produced by a pulsed xenon flash lamp and filtered by
a set of four interference mirrors (excitation filter) which transmit light
between 195 - 235 nm.
The emission filter is a combination of two band pass filters.
It selects light between 340 and 410 nm before the emitted radiation
reaches an orthogonally oriented photomultiplier tube.
A photo detector monitors the light from the lamp. Its signal is
compared to a reference signal and used to control the lamp intensity.

2 Clean or Replace Dust filters Weekly check particle deposits
3 Clean or Replace fan protection filters Weekly High internal temp of analyser
4 Clean Capillaries Once in a month dropped flow rates even with good pump
5 Clean Optics
Best results are obtained when
optics is cleaned prior to
calibration, typically once in six
months.
Cleanliness of the mirrors should be
checked anytime AGC intensity drops
below 200,000 Hz.
6 Replace IR Source
IR Source have a finite life, since it is
relatively inexpensive and easily
replacable, we recommend
replacing it annually.
There is no light output or even after
cleaning the optics IR intensity
remains lower than 100,000hz.is
7 System Leak Checks, replacement of Solenoid
valves Annually
even when pump diaphragm is good and
capillaries not blocked; if plugging
inlets takes more than 60 sec for
pressure value to drop below 250mm
Hg.
8 Pump rebuilding Annually even after cleaning Capillaries if flow is
below 0.350LPM
Caution: Optical mirrors are easy to scratch, this may lead to harm than any good.
84
Troubleshooting
Here are a few of the best things to do/know when troubleshooting our I/R Instruments.
1. When you request AGC Intensity, the most critical Intensity to have is the AGC OFF Intensity.
This is obtained in the service menu under intensity check. It will first show you the AGC Intensity
then you can
toggle the AGC off. AGC off Intensity should be no lower than 150,000 Hz. 200,000 Hz is Typical
with the AGC On.
This must be obtained while flowing zero air.
2. When ever you get the background limit error, the first thing you should check is in service
mode go to Initial S/R Ratio.
If the unit is a 48C, the S/R Ratio must be between 1.13 - 1.19 with Zero air flowing.
The Initial S/R Ratio must be set to what the Current S/R Ratio is reading.
For Example: If the Current is 1.14 and the Initial is 1.17.
Change the initial S/R to be equal to the Current which is 1.14.
They should both now be reading 1.14 as an example.
When these two numbers are not close together, you will get the background error.
Note: If the Current S/R Ratio is out of our tolerance of 1.13 - 1.19, here are some things that
could make it low.
A: Dirty Gas Correlation Wheel
B: Wheel needs to be replaced.
C: The unit may have a purge housing around the wheel and the purge air is not CO Free.
D: A bad Interference Filter.

Mass Concentration Calculation
Based upon mass concentration (MC) measurements obtained during
the base and reference periods, the FDMS system updates a one-hour
average of the following results every six minutes :
Base mass concentration (Base MC) = PM concentration of the
particleladen sample stream (comparable to the Sample Equilibration
System at 30° C).
Reference mass concentration (Ref MC) = PM concentration of the
particle-free sample stream, after passing through the purge filter.
Mass concentration (MC) = Base mass concentration (Base MC)
adjusted by the reference mass concentration (Ref MC) — Base MC
(usually positive) minus Ref MC (negative when mass volatilizes from
the filter).
MC = Base MC - Ref MC

Series 1405 DF
The Series 1405-DF Monitor is composed of two major
components (Figure 1-1):
the sample inlet assembly with virtual impactor and the
Series 1405-DF unit with FDMS system. The user
enters the system parameters into the Series 1405-DF
unit using a color touch screen that is located on the
front of the unit. Additionally, the system is furnished
with software for personal computers (PCs) to allow
the user to download data and update instrument
firmware. The instrument does not require a dedicated
computer to function in the field.

TEOM Series 1405
The Series 1405-D Monitor is composed of two major components: the sample inlet assembly with virtual impactor and the Series 1405-D unit. The user enters the system parameters into the Series 1405-D unit using a color touch screen that is located on the front of the unit. Additionally, the system is furnished with software for personal computers (PCs) to allow the user to download data and update instrument firmware. The instrument does not require a dedicated computer to function in the field.
The sensor unit contains the two mass measurement hardware systems that continuously monitor both fine and coarse particulate. PM Coarse and PM fine particulate, split by a virtual impactor, each accumulate on the system’s exchangeable TEOM filters. By maintaining a flow rate of 1.67 l/ min through the coarse particulate flow channel and 3 l/min through the fine particulate channel, and measuring the total mass accumulated on each of the TEOM filters, the device can calculate the mass concentration of both the fine and coarse sample streams in near real-time.
The sampling system consists of a size-selective inlet, flow splitter
