PAK Marker is especially developed to detect Polycyclic Aromatic Hydrocarbons.
How to Use PAK Marker
Clean the material that is to be tested and ensure that the surface isn't too moist. Best results are obtained when the aerosol and the material to be tested are both at room temperature.
Shake the spray can for a few minutes and then spray a layer of the white spray onto the test material. Let the spray dry.
If there are PAKs (Polycyclic Aromatic Hydrocarbons) present in the material there will be a yellowish/light brown discolouration showing in the white sprayed area. If the discolouration is clear then you can assume that the examined material has more than 150ppm of Polycyclic Aromatic Hydrocarbons present.
If there is any doubt of visible discolouration then an Ultra Violet lamp may be used. Under Ultra Violet light the parts with PAKs present will show up as a yellow/green color. This test is best carried out in a dark environment or in a UV-box.
See BM506 Ultra Violet Lamp.
Please note: The PAK Marker gives an indication if PAK’s are present. It is not a measurement.
