PAS 87

Article: 00097781

Gas analyzer / ammonia / laser / benchtop

The new PAS 87 analyzer is a sub-ppb Ammonia (NH3)
monitoring system dedicated to atmospheric pollution
monitoring and environmental control. This robust ammonia
analyzer offers reliable online measurements in remote
locations and automatic control of air quality.

Environmental applications.
Ammonia has been recognized as
an atmospheric pollutant in Europe
since the 1979 Convention on Long-
Range Transboundary Air Pollution.
In the environment, the presence of
acids, ammonia and water leads to
the formation of ammonium salts such
as Ammonium nitrate (NH4NO3) or
Diammonium sulfate ((NH4)2SO4),
which greatly contribute to the NHx
load and the formation of inorganic
secondary aerosols (an important
component of fine dust - PM10).

High dynamic measurement
of NH3 is
needed for validating
the Long Range
Transboundary Air
Pollution models and
could lead to an
improvement of the NHx
transportation and
deposition models.
