Abstract:
Systems and methods of analyzing one or more properties of a sample are disclosed. One system includes a self-contained purging device having a sample holder and one or more analyzers for analyzing one or more properties of the sample. The purging device is configured to remove sample contained within the sample holder when an analysis is complete. In one embodiment the purging device is configured via an air pump having a tube in fluid communication with an air inlet of the sample holder, wherein the air pump is configured to deliver pressurized air to the air inlet and thereby purge the sample. The pressurized air is localized ambient air, and substantially free of contaminants.
Abstract:
A surface chemistry measuring apparatus (1) includes a processor, an array of tunable infrared laser spectrometers interfacing with the processor and configured for simultaneous measurement of surface chemistry across a surface be measured (25) using a range of infrared wavelengths and a display (8) interfacing with the processor and adapted to display IR spectra of infrared wavelengths reflected from the surface to be measured (25).
Abstract:
A method and apparatus is provided for determining a property of an analyte using a sensing layer whose optical response changes with the analyte. The apparatus includes a housing with an optically transparent window for receiving the sensing layer. The window passes optical stimulation to the sensing layer and the optical response from the sensing layer. A stimulating light emitter is coupled to a first face of an optical body monolithically coupled to the window and a light detector is coupled to a second face of the optical body for receiving the response. The optical response changes as the concentration of the analyte changes. Reference molecules included in the sensing layer can provide a calibration signal to a second light detector mounted on a third face of the optical body. The first, second and third faces of the optical body are different and not coplanar.
Abstract:
A limited access space inspection system comprising: a sensing device for carrying out sensing over a region in the limited access space, a mounting for mounting the sensing device to scan about the limited access space and a scanning control unit, associated with the sensing device, for controlling the sensing device to scan about the limited access space. The device is particularly useful for improving by automation, security checks, customs checks and safety checks involving such awkward to access spaces. The sensing device may be an imaging device, or a sensor for detecting traces of chemical substances.
Abstract:
A breath analysis system that includes a handle assembly with an analysis cartridge on an upper end thereof. The handle includes a main body portion with a pressure opening and a pressure transducer therein. The analysis cartridge includes a main body portion with an upper portion that defines a breath chamber, a lower portion that defines a fluid chamber and a filter assembly that is movable between a breath capture position and an analysis position. The filter assembly has an opening defined therethrough. In the breath capture position, the opening partially defines the breath chamber and in the analysis position the opening partially defines the fluid chamber. The system also includes an analysis device with door, a controller that controls the motor and a fluorescence detection assembly and a rotation assembly positioned in the case interior. The rotation assembly includes a shroud with a funnel portion for receiving the analysis cartridge.
Abstract:
The invention relates to a receptacle (4) for receiving a sample (5) during an optical analysis of the sample (5), wherein the receptacle (4) comprises a bottom (19) which is at least partially transparent so that the sample (5) within the receptacle (4) can be optically analyzed by an image sensor (6) from below the bottom (19) and wherein the bottom (19) is very thin thereby improving contrast and sharpness of the images generated by the image sensor (6). Further, the invention relates to a system for optically analyzing a sample (5).
