Abstract
In one aspect, an apparatus includes a head configured to receive a pad for sampling explosive residue on a surface and a feedback system coupled to the head. The feedback system is configured to indicate when a pressure applied by the head is greater than a minimum threshold value. In another aspect, an apparatus includes a head configured to receive a pad and rotate to apply a shear force to the pad for sampling explosive residue on a surface. The apparatus includes a feedback system coupled to the head, which is configured to restrict the shear force applied by the head to be within a predetermined range. In another aspect, a method includes applying pressure to a pad to sample explosive residue on a surface, sensing the pressure applied to the pad, and providing an indication of when the pressure applied to the pad is greater than a threshold value.
