ECM systems for ambient air monitoring are usually built into air-conditioned thermally insulated containers. Monitoring stations can be stationary or mobile.
The usually monitored gaseous pollutants are:
Automated Ambient Air Mercury Analyzer
Mercury analyzer for continuous monitoring with unrivaled accuracy, sensitivity and reliability.
Key features:
- Low detection limit <0.1 ng / m3
- Internal permeation tube for automatic calibration
- Dual-channel gold absorber for continuous sampling
- Low operating costs
Aerosols are monitored in accordance with TSP, PM10, PM2.5 or PM1 regulations.
Simultaneous monitoring and sampling of different fractions. Certified dual-channel particle monitor combined with a
certified sampler and an 8-channel optical module with
continuous output of individual fractions.
Samplers allow the storage of aerosol samples for later
analysis of heavy metals or other contaminants.
Aethalometer
The Aethalometer TM is an ideal instrument for measuring the content of total or elemental carbon in
airborne dust.
An aethalometer is an instrument that uses continuous sampling and optical analysis technology to
measure carbon concentration in near real time.
OC/EC analyzers
Thermal OC / EC analyzers with laser pyrolysis correction and compatibility with the standard NIOSH 5040 method.
Ultrafine particle TSI monitor
Continuous monitoring of ultrafine particles (UFP) and air quality monitoring (SMPS).
Features and advantages:
- Designed for continuous operation
- Technology according to CEN / TS 17434
- Fast scan time
- Portable but also stationary
- No radioactive materials
Compact instruments for monitoring PM10, PM2.5 and PM1
airborne dust fractions. Particle counter allowing to define 16 size channels, with display of the number of particles and
at the same time their mass concentration.
On-line monitoring of heavy metals in dust aerosols
The device works on the principle of XRF and performs on-line analysis of metals contained in
dust aerosols. It is designed for unattended continuous operation in air monitoring stations.
To increase the accuracy and stability of measurement the stations are
equipped with internal air conditioning of the sensor space and heating
of dust components for correct measurement even during foggy and
rainy days. The reliability of the measurement of gaseous components
is ensured by periodic calibration using reference gases from pressure
cylinders.
AQMesh monitoring modules are compact, allowing power from
batteries or solar cells.
Information from the sensors is transmitted over the mobile network to
a central server, where it is interpreted for pollutant concentrations and
made available to customers via the Internet. The reliability of the
measurement is verified by comparison with a reference monitoring
station, where it adjusts the interpretation algorithms in the central
server.
If you are only interested in measuring airborne dust, simplified
versions of stations are available that measure only dust, or dust and
one gaseous component.
Odor
In addition to the individual gaseous components, we often encounter interest in measuring odors.
The human nose is more sensitive to some smelly substances than most devices.
Olfactometers are used to evaluate odorous substances and analytical instruments are also
available for their continuous evaluation.
Vehicle emissions
Air pollution from transport is a significant problem. New analytical instruments allow remote
measurement of pollution from each passing vehicle during normal traffic.
Sampling for laboratory analysis
Reference sampling devices for dust or gaseous
components make it possible to determine
accurately the concentration of pollutants such as
heavy metals, hydrocarbons and other pollutants in
laboratories.
