摘要： 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.

摘要： Screening of items for the presence of contaminants, such as explosives residue, is accomplished by subjecting an item loaded into a pressure chamber to a pressure substantially in excess of atmospheric pressure conditions and rapidly decompressing the item to the ambient atmospheric pressure. The rapid decompression serves to scavenge vapors and particles from the exterior and interior of the item and any objects it contains. A sample of the vapors and particles removed from the item by the rapid decompression is sampled and is tested to determine whether a predetermined contaminant is present in the sample. Depending on the types of contaminants for which the sample is tested, it is possible to detect whether explosives, biological or chemical agents, and/or narcotics residues are present on or in the item being screened.
摘要翻译：通过对装载到压力室中的物品施加基本上超过大气压力条件的压力并将物品快速减压至环境大气压来实现污染物（例如爆炸物残渣）的存在的筛选。快速减压用于清除物品的外部和内部以及其包含的任何物体的蒸气和颗粒。对通过快速减压从物品中除去的蒸气和颗粒的样品进行采样，并进行测试以确定样品中是否存在预定的污染物。根据测试样品的污染物类型，可以检测爆炸物，生物或化学物质和/或麻醉剂残留物是否存在于待筛选的物品上。
