What is Gaseous
Pollutant Sampler
A Gaseous Pollutant Sampler is an instrument used to
collect and measure harmful gases in the air, such as
SO₂ (Sulfur Dioxide), NO₂ (Nitrogen Dioxide), CO
(Carbon Monoxide), O₃ (Ozone), VOCs (Volatile Organic
Compounds), and NH₃ (Ammonia). These devices are
essential for environmental monitoring, industrial
emissions assessment, and regulatory compliance.
Exploring creativity
Why is it Important?
Air pollution is a global concern
affecting human health and
climate.
Governments & industries use
these samplers for regulatory
compliance.
How its work
1. Air Collection
A vacuum pump pulls air into the
sampler.
Air passes through a special absorption
medium (liquid or solid) to capture
gases.
2. Gas Collection Methods
Wet Method (Impingers) – Uses chemical
solutions to absorb gases.
Example: NaOH absorbs SO₂, KI absorbs O₃.
Dry Method (Adsorption Tubes) – Uses
solid sorbents (activated carbon, silica gel)
to trap gases like VOCs, CO₂, NH₃.
3. Chemical Analysis
Collected gases are analyzed using
Spectrophotometry, GC-MS, or
Electrochemical Sensors.
Some samplers provide real-time digital
readings for quick monitoring.
What is the Use
A Gaseous Pollutant Sampler is
used to monitor, measure, and
analyze harmful gases in the
air for environmental,
industrial, and health safety
applications.
Gas Source Impact
SO₂ (Sulfur Dioxide) Factories, Vehicles Respiratory Issues
NO₂ (Nitrogen
Dioxide)
Traffic, Power
Plants
Lung Diseases
CO (Carbon
Monoxide)
Incomplete
Combustion
Toxic to Humans
O₃ (Ozone) Chemical Reactions
Eye & Lung
Irritation
VOCs (Volatile
Organic
Compounds)
Paints, Industry Carcinogenic
Types of Gases Measured
Advantages & Limitations
Advantages
Accurate & reliable air
pollution measurement.
Helps enforce
environmental laws &
worker safety.
Available in portable &
fixed versions.
Some require lab analysis
(not real-time).
Maintenance &
calibration are needed.
Can be expensive for
long-term monitoring.
Limitations
Helps in pollution control &
health safety.
Used in industries, cities,
and scientific research.
Ensures cleaner air &
regulatory compliance.
Conclusion
Why Gaseous Pollutant
Sampling is Important?
