Abstract:
An image based photometer includes a light source adapted to hold a well plate having multiple wells for testing samples, the light source providing a source of broadband white light for transmission through the multiple wells. A sensing surface is positioned opposite the light source to receive light transmitted through the multiple wells and shield ambient light from transmission through the wells.
Abstract:
One aspect of the present disclosure relates to an analyte sensor device. The analyte sensor device can include an optode layer that undergoes an optical change in the presence of an analyte. The analyte sensor device can also include a selectively-permeable membrane encapsulating the optode layer to form a stable membrane that that minimizes fouling of the analyte sensor device. The analyte sensor device can also include a plurality of microparticles that suppress a background physical interference on a detection of the optical change of the optode layer.
Abstract:
A clam-shell luminometer that, when closed, completely encloses an assay reaction mixture-containing reaction vessel and some portion of a reaction carousel or ring. The luminometer includes first and second portions that are coupled to each other, a photomultiplier tube, and plural fiber optic bundles that are optically coupled to the photomultiplier tube. First ends of the fiber optic bundles are disposed adjacent to the reaction vessel in the second portion so that the fiber optic bundles completely surround the perimeter or periphery of the reaction vessel.
Abstract:
Optical computing devices are disclosed. One optical computing device includes an electromagnetic radiation source that emits electromagnetic radiation into an optical train to optically interact with a sample and at least one integrated computational element, the sample being configured to generate optically interacted radiation. A sampling window is arranged adjacent the sample and configured to allow transmission of the electromagnetic radiation therethrough and has one or more surfaces that generate one or more stray signals. A first focal lens is arranged to receive the optically interacted radiation and the one or more stray signals and generate a primary focal point from the optically interacted radiation. A structural element defines a spatial aperture aligned with the primary focal point such that the optically interacted radiation is able to pass therethrough while transmission of the one or more stray signals is substantially blocked by the structural element.
Abstract:
System and method for detecting and counting bacteria suspended in a biological fluid by means of light scattering measurements is provided. In accordance with the method of the invention the level of signal to noise of the measured intensities of light scattered by a sample of the biological fluid is significantly enhanced for forwardly scattered light within a range of scattering angles which are smaller compared to a predefined maximal scattering angle. The system of the invention includes a cuvette adapted to contain a sample of the biological fluid whose sidewalls and windows are suitably constructed and arranged to significantly reduce the level of reflected light obscuring the scattering patterns measured within the range of scattering angles considered.
