Dust is usually dense with particles such as textile fibres, skin cells, pollen, asphalt or concrete. This means that shoe soles covered in dry dust can give off excellent dustprints on floor and paper. These prints may be lifted by applying an electrostatic charge. Our dustprint lifter, the eDust+, is designed to generate good results on most surfaces.
The eDust+ works with different surfaces. Under normal conditions, the built-in grounding and high voltage connectors may be used to lift a print from a floor. If the electrical ground is poor, like on a plasterboard, you can use the loose grounding cable, the high voltage probe and a lifting film. Put a piece of the lifting film under the object to improve the ground.
If a particular surface, like a wooden or plastic floor, does not provide enough grounding connection, there are ways to increase the ground voltage. Use an additional piece of lifting film, approximately 30 x 40 cm in size and place it with the silver side facing the floor roughly 3 to 4 cm away from the main piece of lifting film, and overlapping a small part of the ground plate. Proceed to use the eDust+ unit in the normal operating way.
Once you have lifted a dustprint onto the film, it will not be released from the film if physical touch is avoided. Avoid touching the film then roll it back onto the cardboard tube and bring it to the lab for comparison.
The eDust+ can be used on surface areas of varying sizes. If you wish to lift dust from a larger area, just release more lifting film from the roll. Make sure that the ground is adequate and reinforce the ground using the technique described above if necessary.
