SET OF QUICK TESTS FOR PRESENCE OF EXPLOSIVE MATERIALS Russian patent published in 2018 - IPC G01N33/22 G01N31/22 

FIELD: measuring equipment.

SUBSTANCE: invention relates to devices for the study and analysis of non-biological materials by chemical indicator means for the purpose of rapid detection of explosive residue in a contact test portion, including during examinations in an off-laboratory environment. The quick tests set for the presence of explosives consists of a portable plastic container equipped with an internal cushioning insert with functional recesses, including recesses for installation of microcolumns, bottles with solutions placed in the recesses, as well as micro-column test systems for detecting the presence of chlorates and perchlorates, cases with rolls tapes of reactive indicator materials containing reagents immobilized on the surface of the carrier. Cases with rolls of tapes of reactive indicator materials consist of a body made of an elastic inert material in the form of hollow cylinders with a coaxial cap tightly adjacent to the cylindrical surface. The side walls of the cases have longitudinal slots through which the edge of the tape passes, and in addition, the body and the cover have mutual angular mobility around the axis, providing, when their longitudinal slots are aligned along one line, before the open window is formed, the function of opening the case with release of the edge of the tape, or mutual overlapping of their longitudinal slots function of hermetic sealing of the case with fixation of the edge of the tape.

EFFECT: higher safety of use and simplified operation.
