ABSTRACT:
A hand-held device for rapid colorimertic detection of explosives, narcotics, and other chemicals which can be accurately operated by non-skilled personnel and perform numerous tests in a quick sequential manner without exposing a user to hazardous reagents and without exposing sensitive reagents to deteriorating environmental conditions, the device comprising (a) a housing for handling and using the device, the housing including a sampling area an a testing area; (b) a roll of substrate for sampling materials suspected as including the chemical; (b) a feeding reel being rotatably connected to the housing, the feeding reel being for accommodating the roll of substrate; (c) at least one container for accommodating at least one detecting reagent, the at least one detecting reagent is for the colorimetric detection of the chemical; and (d) at least one dispensing mechanism for dispensing a predetermined volume of the at least one reagent onto the substrate at the testing area.
