The present invention discloses darkroom type security inspection apparatus and method. An apparatus comprises a housing constituting a closed darkroom, and assemblies disposed inside the housing. The assemblies disposed inside the housing are communicated by fittings or connectors and comprises: a sampling assembly comprising a sample collecting unit and a conveyer unit configured to convey an object to be inspected into the sample collecting unit; a sample processing assembly configured to concentrate and analyze the sample; and, an inspecting assembly configured to inspect composition of the sample by means of a gas chromatographic-ion mobility spectrometer (GC-IMS) or a separated ion mobility spectrometer (IMS). The security inspection apparatus of the present invention can perform the sampling easy, rapidly and effectively and perform the inspection accurately and rapidly without destroying and unpacking an object to be inspected, and thus is suitable for requirements of on-site rapid inspection of forbidden items in the airport, customs and the likes.

Disclosed are a highly selective, highly sensitive method and apparatus for detecting vapors from explosives at low concentrations such as 1 part in 10.sup.14. Airborne explosives vapors are selectively adsorbed on a spiral-wound platinum or platinum-coated ribbon of a preconcentrator cartridge while trapping of nitrogen oxides is avoided. The vapors are released and partially decomposed to liberate nitric oxide gas by flash-heating of the ribbon, these products may then be pyrolyzed if necessary to complete the liberation of nitric oxide gas, and then the liberated nitric oxide gas is detected, as by chemiluminescent detection. Also described are various systems incorporating the explosives vapor detector such as a walk-through portal, a vehicle sniffer, and a system incorporated into the air-handling apparatus of a building. A walk-through explosives detection system is disclosed having a carousel containing an array of preconcentrator cartridges for rapid acquisition and analysis of explosives vapor samples, and which is capable of screening up to ten persons per minute for possession of explosives.

The present invention relates to roadside analyzer for determination of illegal drugs abuse, including, but not limiting to detection of explosives, toxic industrial chemicals and other banned or regulated compounds, biomarkers and phytochemicals in a sample in situ in at least one human body fluid sample, specifically in oral fluid (saliva), but not limiting to other clinical samples of interest (urine, blood, exhaled breath, exhaled breath condensate, etc.) It consists of automatic processor for preparing samples suitable for analysis. Analysis part of the instrument implements three technologies, namely solid phase extraction prior to analysis, capillary electrophoresis for separation of analytes from the sample matrix and impedance (contactless conductivity) or fluorescence or both impedance (contactless conductivity) and fluorescence for detection of analytes of interest.

In order to save a space for an apparatus for inspecting a substance and reduce a cost thereof, a particle testing apparatus includes a plurality of collection ports for collecting substances to be inspected, centrifuges for concentrating particles collected in the collection ports, the centrifuges being connected to the respective collection ports in pairs, and a common analysis apparatus for acquiring the concentrated particles from the centrifuges and analyzing the particles, the analysis apparatus being connected to the centrifuges.

The present invention discloses a wiping-type sample sampling and feeding device, a card reading apparatus, and a gate machine apparatus. The wiping-type sample sampling and feeding device comprises a thermally desorbing portion for analyzing a substance; a wiping-type sampling portion for wiping the substance on a card or certificate and includes a first wheel, a second wheel and a wiping conveyor belt that travels between the first and second wheels along a first direction; and a card/certificate conveyor portion including a card carrying belt configured to convey a card or certificate along a second direction so that the card or certificate can contact with the wiping conveyor belt during conveyance of the card or certificate, thereby the wiping conveyor belt wipes a surface of the card or certificate, wherein the second direction is substantially perpendicular to the first direction.

A scanning system is for trace detection. The scanning system includes a main body enclosing a scanning chamber, the main body including a chamber inlet; a transport system configured to move an article through the scanning chamber along a scanning path; and a door mechanism provided along the scanning path. The door mechanism includes: a door frame mounted about the scanning path; at least one door panel movable relative to the door frame and being made of a radiation-shielding material; and a trace detector integrated into the at least one door panel. A method for trace involves using trace detectors integrated into the door mechanism for trace detection while the object is moving along a scanning path passing through a scanning chamber of a scanning system.

The apparatus disclosed herein pertains to the detection of trace explosives or narcotics detection. The apparatus comprises the front-end particle dislodge and sample intake portion of a chemical trace detection system utilizing aerodynamic flow as a transport mechanism whereby compounds indicative of explosives or narcotics contamination are liberated from target surfaces of foot or footwear and then transported by air flow to a sample accumulation feature for chemical analysis. The apparatus is intended for inclusion with additional components, such as an efficient pre-concentrator, a thermal desorption unit, and a chemical analyzer/detector to achieve a complete trace detection system.

A test kit is provided. The test kit includes a case including a plurality of reagent containers storing reagents, each reagent indicating the presence of a substance when the reagent comes into contact with that substance. The test kit further includes a collector including a collector body, and a plurality of swabs coupled to the collector body and configured to collect substances. The test kit is configured to test for a plurality of collected substances by causing the reagents stored in the plurality of reagent containers to contact at least one of the plurality of swabs, and the test kit is further configured to display results of the test.

A test kit is provided. The test kit includes a case including a top including a plurality of indicator pads and a crushing plate rotatable between a first position and a second position, the crushing plate including a plurality of crushing ribs. The case further includes a bottom hingedly coupled to the top, the bottom including a plurality of reagent ampoules storing reagents. When the case is closed with the crushing plate in the second position, the plurality of crushing ribs crush the the plurality of reagent ampoules. The test kit further includes a collector including a collector body, a plurality of swabs extending through the collector body, a removable cover covering a first side of the collector body, and a collector handle coupled to the collector body, wherein the collector is nestable within the case.

Provided is a technique to identify a sample substance attached to an inspection target easily and precisely, while improving the rate of operation and reducing the number of persons required for inspection. A trace detecting system includes detection means to detect the size (vertical and horizontal dimensions) of an inspection target, and selects an air nozzle capable of spraying air jet at 15 m/s or more to the surface of the inspection target for air jet spraying.
