This sampling is done in isokinetic conditions and typicallythis kind of pollutants are catched by using glass impingersfilled with a specifical chemical solution where the flue gas issucked through a pump and a heated probe. Our solution consists in a sampling train composed by aheated probe X1-Probe with a titanium sampling line and aglass filter holder in order to have inert materials in directcontact with the flue gas without influencingthe analysis results. The isokinetic sampling is driven by the isokinetic controllerlIsocheck SRB together with a Lifetek Pump series， alightweight， versatile and user friendly solution. Thanks to E1-Analyzer it is possible to measure the dry gasdensity and use the real value for the isokinetic calculations. < ISOCCHHECK CARE FOR THEENVIRONMENT METALS UNIEN 14385：2004 The reference standard for sampling of metals in stacks isUNI EN 14385：2004. “Stationary source emissions. Determination ofthe totalemission of As， Cd， Cr， Co， Cu， Mn， Ni， Pb， Sb， Tl and V".The system allows to sample heavy metals in flues of any sizeand type (vertical/horizontal). 5 LEGEND 1.X1-Probe 2.
