Abstract

An explosion tester system comprising a body, a lateral flow membrane swab unit adapted to be removeably connected to the body, a first explosives detecting reagent, a first reagent holder and dispenser operatively connected to the body, the first reagent holder and dispenser containing the first explosives detecting reagent and positioned to deliver the first explosives detecting reagent to the lateral flow membrane swab unit when the lateral flow membrane swab unit is connected to the body, a second explosives detecting reagent, and a second reagent holder and dispenser operatively connected to the body, the second reagent holder and dispenser containing the second explosives detecting reagent and positioned to deliver the second explosives detecting reagent to the lateral flow membrane swab unit when the lateral flow membrane swab unit is connected to the body.

Claims (8)

1. An inspection tester method for testing a suspect surface for explosives wherein the explosives are explosives particles, consisting of the steps of:

providing an explosives detecting lateral flow membrane with polyethylene spheres fused into said membrane for collecting the explosives particles,

providing a lateral flow membrane swab unit containing said explosives detecting lateral flow membrane with polyethylene spheres fused into said membrane for collecting the explosives particles,

providing a first explosives detecting reagent;

providing a second explosives detecting reagent;

swiping the suspect surface with said lateral flow membrane swab unit containing said explosives detecting lateral flow membrane with polyethylene spheres fused into said membrane for collecting the explosives particles wherein the explosives particles are picked up by said lateral flow membrane swab unit containing said explosives detecting lateral flow membrane with polyethylene spheres fused into said membrane for collecting the explosives particles,

delivering said first explosives detecting reagent to said lateral flow membrane swab unit containing said explosives detecting lateral flow membrane with polyethylene spheres fused into said membrane for collecting the explosives particles and the explosives particles picked up in said step of swiping the suspect surface and producing a solvent front concentrating the explosives particles along said solvent front and concentrating the explosives particles in one place, wherein if said lateral flow membrane swab unit containing said explosives detecting lateral flow membrane with polyethylene spheres fused into said membrane for collecting the explosives particles becomes colored the test is positive for explosives and if no color appears the test for explosives is negative to this point; and

delivering said second explosives detecting reagent to said lateral flow membrane swab unit containing said explosives detecting lateral flow membrane with polyethylene spheres fused into said membrane for collecting the explosives particles, wherein if said lateral flow membrane swab unit containing said explosives detecting lateral flow membrane with polyethylene spheres fused into said membrane for collecting the explosives particles becomes colored the test is positive for explosives and if no color appears the test for explosives is negative.
