A user opens a detection kit, swabs a surface or surfaces with the bundled sticks, collecting chemical constituents to be tested on detection surfaces of each of the plurality of sticks. Liquids, mists, vapors and powders may be tested in one method, utilizing one or more dry reagents on the detection surfaces. The sticks may comprise a volume of fluid, releasably contained within the sticks, such that when activated, a fluid, such as a reagent or solvent, is wicked by a wicking tip to the detection surface of the stick. For example, a mechanism is provided that is capable of breaking a vial or ampoule containing the fluid, when activated by a twisting motion or compression. Adhesive may be present on one or more of the detection surfaces.
