Various techniques are provided to secure a memory polymer component in a flow path. In one embodiment, a method includes providing a memory component in a rest state, performing a deformation operation to transition the component from the rest state to a deformed state, inserting the component into a flow path defined by interior side walls of a structure, and applying a stimulus to transition the component from the deformed state to an intermediate state in which the component abuts the side walls to secure the component in the flow path. Additional devices, systems, and related methods are also provided.

Retention of deformable memory material in flow path

Various techniques are provided to determine the presence of trace chemicals corresponding to various materials of interest. In one example, a method includes receiving a vapor-phase nitric acid precursor. The vapor-phase nitric acid precursor is subsequently hydrolyzed in the presence of an acid catalyst to form nitric acid. The nitric acid is then received at a chemical reporter of a chemical detector. A response of the chemical reporter to the nitric acid is detected by the chemical reporter to determine whether materials of interest are present. Additional methods and related devices are also provided.

Enhanced chemical detection using acid catalyzed hydrolysis

A detector for detecting vapors emitted from analytes includes a housing, a pump and a sensing assembly. The housing has an inlet, an outlet and an enclosed sensing volume therebetween. The pump communicates with the housing for moving a carrier sequentially through the enclosed sensing volume at a predetermined flow rate. The sensing assembly senses the vapors of the analyte delivered by the carrier as the carrier passes through the housing. The sensing assembly includes a sensing unit constructed of an amplifying fluorescent polymer, a source of excitation, a detector, and a convertor assembly.

Vapor sensing instrument for ultra trace chemical detection

The current invention provides a passive sampling device suitable for collecting and detecting the presence of target analytes. In particular, the passive sampling device is suitable for detecting nitro-aromatic compounds. The current invention further provides a passive sampling device reader suitable for determining the collection of target analytes. Additionally, the current invention provides methods for detecting target analytes using the passive sampling device and the passive sampling device reader.

Discreet passive explosive detection through 2-sided wave guided fluorescence

The present invention provides improved preconcentrator media suitable for selectively desorbing captured analytes. Additionally, the current invention provides improved methods for concentrating trace quantities of analytes to a degree suitable for detection by a detecting device.

Vapor sensing instruments for ultra trace chemical detection

A detector for detecting vapors emitted from energetic compounds includes a housing, a pump and a sensing assembly. The housing has an inlet, an outlet and an enclosed sensing volume there between. The pump communicates with the housing for moving a carrier gas sequentially through the enclosed sensing volume at a predetermined flow rate. The sensing assembly senses the vapors of the energetic compound delivered by the carrier gas as the carrier gas passes through the housing. The sensing assembly includes a sensing unit constructed of an amplifying fluorescent polymer, a source of excitation, a light detector, and a convertor assembly.
