Abstract:
A system for the continuous detection of microbes of interest in waters, comprising: - at least one biosensor tank (1) having an inlet (2) and an outlet (3) for the waters to be monitored and containing nanoparticles (14) functionalised with at least one antibody specific for the antigenic capture of a particular type of microbe present in the water, and the creation of networks that give rise to an agglutination reaction that creates turbidity in the water, captured by a spectrophotometric sensor (17) or sensor for the measurement of the turbidity in the water, and - a control unit (4) for monitoring, logging, and processing the information provided by the spectrophotometric sensor (17) or sensor for the measurement of turbidity; and for monitoring the operation of the system.
Abstract:
A metrology system includes an illumination source configured to generate an illumination beam, one or more illumination optics configured to direct the illumination beam to a sample, one or more collection optics configured to collect illumination emanating from the sample, a detector, and a hyperspectral imaging sub-system. The hyperspectral imaging sub-system includes a dispersive element positioned at a pupil plane of the set of collection optics configured to spectrally disperse the collected illumination, a lens array including an array of focusing elements, and one or more imaging optics. The one or more imaging optics combine the spectrally-dispersed collected illumination to form an image of the pupil plane on the lens array. The focusing elements of the lens array distribute the collected illumination on the detector in an arrayed pattern.
Abstract:
In some aspects, a device for apportioning granular samples includes a sample feeder defining a conduit, the conduit including a first opening to receive the granular samples and a second opening. The device includes a shuttle operably coupled to the sample feeder to receive the granular samples from the conduit via the second opening. The shuttle is configured to apportion the granular samples to incrementally enter a sample chamber to be analyzed. The device includes an outlet conduit fluidly coupled to the sample chamber and configured to permit the sample chamber to be evacuated.
Abstract:
An optical analysis tool includes an integrated computational element (ICE). The ICE includes a plurality of layers stacked along a first axis. Constitutive materials of the layers are electrically conductive and patterned with corresponding patterns. An arrangement of the patterns with respect to each other is related to a characteristic of a sample.
Abstract:
An optical analysis tool includes an integrated computational element (ICE). The ICE includes a first hollow-core fiber. The first hollow-core fiber has a structure configured such that a spectrum of light guided by the first hollow-core fiber is related, over a wavelength range, to a characteristic of the sample.
Abstract:
Disclosed is the detection of emulsions and microdispersions with an optical computing device. One disclosed method includes emitting electromagnetic radiation from an electromagnetic radiation source, optically interacting the electromagnetic radiation with a fluid and thereby generating fluid interacted radiation, detecting a portion of the fluid interacted radiation with a reference detector arranged within an optical channel of an optical computing device, generating a reference signal with the reference detector, and determining an emulsive state of the fluid based on the reference signal.
