Problems solved by technology

Therefore, the cost of providing the separate devices needed to identify chemical and biological substances can be prohibitively expensive for smaller communities
In addition, first responders must bring a variety of devices to the scene of the investigation along with other equipment used by first responders, thus increasing the time and effort required to screen large facilities for unidentified substances

Embodiment Construction

[0017] The present invention provides a hand-held integrated device or instrument to assist in assessing the chemical composition and / or biological properties or identity of unknown substances or sample portions of unknown substances in order to identify potential chemical threats and / or potential biological threats. The substance may be contained within a sealed container, within a transparent or translucent container, or the substance may be coated with a layer of material. In one embodiment, the device employs Raman spectroscopy to help identify the chemical composition and / or biological properties or identity of unknown substances. The device employs a laser excitation beam of appropriate wavelength, such as about 1 micron, to provide high resolution sample identification while eliminating or reducing sample fluorescence. The device can also pre-screen samples of unknown substances in order to identify potential biological threats. After identifying a potential biological...

Abstract

A device for identifying an unknown substance includes an optical source configured to direct a laser excitation beam at the unknown substance. A detector is configured to detect scattered light from the unknown substance and generate at least one signal representative of a scattering spectrum corresponding to at least one chemical within the unknown substance. A microprocessor is in signal communication with the detector and configured to generate a pattern representative of the at least one chemical in response to the at least one signal received from the detector to identify the chemical composition of the unknown substance. The device is configured to complete a bioassay to identify a biological nature of the unknown substance.

Description

technical field [0001] In general, the present invention relates to apparatus for performing chemical assays and biological assays, and more particularly, to devices configured to perform chemical assays to identify the chemical composition of unknown substances and / or perform biological assays to identify biological properties of unknown substances or An integrated device of identity. Background technique [0002] First responders often encounter a wide variety of unknown substances that must be evaluated using a variety of devices in order to determine whether each unknown substance is a chemical threat, a biological threat, or not. To analyze and identify target substances, first responders often employ a variety of devices or instruments to assess the properties of each specific substance they may encounter on a daily basis. For example, first responders currently use a first device to detect and identify chemical threats and a second device to detect and identify biolo...
