Abstract
A personal-sized, portable explosive detection field test kit (ETK) and related methods of use. Embodiments of the disclosed ETK include a case having a closing system featuring three levels of closure which retain the case cover securely in a closed position until ready for use, while being easily opened when necessary. The ETK instructions are permanently attached to the case to prevent loss. The case includes retention features which retain the kit components until needed and protects them against loss or damage. The ETK includes one or more test tubes that are color coded and include abbreviated instructions.
Claims20
A portable substance detection field test kit, comprising:
- a top cover having a hinge side and a latch side and comprising an instruction card fixed to an inner surface of the top cover, a pocket adapted to retain one or more sheets of test paper, and a ridge extending from the latch side of the top cover;
- a bottom cover having a hinge side and a latch side and comprising at least one cradle on an inner surface thereof configured to selectively retain a drip tube, and a latch face extending from the latch side of the bottom cover having a snap rib protruding from the latch face, wherein the top cover and bottom cover are joined by a hinge along the respective hinge sides thereof forming a housing having an open position wherein the latch sides of the top cover and bottom cover are separated, and a closed position wherein the latch sides of the top cover and bottom cover are joined;
- at least one drip tube;
- at least one sheet of test paper adapted to collect a substance sample;
- and
- a latch assembly, comprising:
- a latch lever having an open position and a closed position;
- a stop rib operatively associated with the latch lever and configured to engage the underside of the latch face when the latch lever is in a closed position;
- and
- a first hook and loop fastener and a mating second hook and loop fastener, wherein the first hook and loop fastener is disposed on an inner surface of the latch lever and the second hook and loop fastener is disposed on a mating surface of the bottom cover, wherein the first and second hook and loop fasteners engage when the latch lever is in a closed position.

- a first hook and loop fastener and a mating second hook and loop fastener, wherein the first hook and loop fastener is disposed on an inner surface of the latch lever and the second hook and loop fastener is disposed on a mating surface of the bottom cover, wherein the first and second hook and loop fasteners engage when the latch lever is in a closed position.
4 more elements
A method of conducting a test to detect the presence of a targeted substance, comprising:
- providing a portable substance detection field test kit, comprising:
- a top cover having a hinge side and a latch side and comprising an instruction card fixed to an inner surface of the top cover, a pocket adapted to retain one or more sheets of test paper, and a ridge extending from the latch side of the top cover;
- a bottom cover having a hinge side and a latch side and comprising at least one cradle on an inner surface of the bottom cover configured to selectively retain a drip tube, and a latch face extending from the latch side thereof having a snap rib protruding from the latch face, wherein the top cover and bottom cover are joined by a hinge along the respective hinge sides thereof forming a housing having an open position wherein the latch sides of the top cover and bottom cover are separated, and a closed position wherein the latch sides of the top cover and bottom cover are joined;
- at least one drip tube containing a reagent solution configured to expose the presence of a targeted substance by causing an initial color of a test sample to change to a predetermined color when the reagent solution is applied to the test sample;
- at least one sheet of test paper adapted to collect a substance sample;
- and
- a latch assembly, comprising:
- a latch lever having an open position and a closed position;
- a stop rib operatively associated with the latch lever and configured to engage the underside of the latch face when the latch lever is in a closed position;
- and
- a first hook and loop fastener and a mating second hook and loop fastener, wherein the first hook and loop fastener is disposed on an inner surface of the latch lever and the second hook and loop fastener is disposed on a mating surface of the bottom cover, wherein the first and second hook and loop fasteners engage when the latch lever is in a closed position;
- removing a sheet of test paper from the pocket;
- wiping a surface to be tested with the test paper;
- removing a drip tube corresponding to the desired substance for which the test is being conducted from its respective cradle;
- dispensing the reagent solution from the drip tube onto the test paper;
- observing a color change on the test paper;
- and
- concluding that the targeted substance is present in the test sample if the color of the test paper changes to the predetermined color.
