Abstract:
1. A colorimetric detection kit for detecting analytes in a suspect sample from an environment, comprising: a detection and visualization unit (DAVU) comprised of four, individually confined cells each containing a visualization surface for receiving a reacted chemical reagent; a sampling and chemical unit (SACU) separate from and placeable adjacent to and juxtaposed against said DAVU, said SACU also comprised of four individually confined cells such that when said SACU is juxtaposed against said DAVU the individual cells of said SACU are juxtaposed against the individual cells of said DAVU, each of said cells of said SACU containing at least one chemical reagent reactive with said analytes, wherein said chemical reagents are contained in breakable containers within each cell of said SACU, and wherein said SACU includes one cell containing reagents useful for detecting urea, one cell containing reagents useful for detecting ammonium, one cell containing reagents useful for detecting perchlorate, and one cell containing reagents useful for detecting nitrate, and said SACU also having a sample collector positioned so as to be capable of receiving said chemical reagents and adjacent to said visualization surface when said SACU is placed against said DAVU; and wherein said sample collector includes an adhesive surface for effectively adhering suspect sample thereto in order to collect a sample from a surface, and wherein said visualization surface displays a color change when receiving said reacted chemical reagents in the presence of at least one suspect analyte.
