Purpose and Application
Longterm sampling of dioxins
The DioxinMonitoringSystem® is mainly used for long term sampling of polychlorinated dibenzo-p-dioxins and
-furans. Usually a one month sampling period is selected. In this case complete sureillance is ensured by doing
12 measurements a year.
Measurements according 2000/76/EG
The European directive 2000/76/EG limits the emitted dioxins to a valku of 0,1ng I-TEQ/m3. Measurements shall
be performed using EN 1948-1.
The DioxinMonitoringSystem® fulfils all the requirements of this standard. Using 6 to 8 hour sampling time,
the device is used to check the legal limit value. This includes the I-TEQ PCDD/F, the I-TEQ PCB andthe legal limit
value of PAHs. Due to the sampling at two positions in thje stack, traversing is not necessary.
Sampling of special components
The dilution method used in this procedure cools the flue gas down to 40°C without condensation and filters all particulates
at that temperature. The cartridge itself is made of non corrosive pure titanium.
This process also enables the sampling of many heavy metals, which are solid at 40°C, like Cr, Ni or Pb. It makes it
possible to sample salts like Na2SO4, CaSO4 quantitatively over longer periods as well.
More: It enables to sample components, which are gaseous in the hot flue gas and soild at 40°C (e.g. NH4Cl,
(NH4)2SO4), on a dry filter. This feature offers the unique opportunity to quantify
the real emissions of "fine dust" and "total Cl".
