Abstract:
A device for dynamic filtration of a pharmaceutical product is provided. The device includes a resin configured to selectively retain one or more components from a mixture having the pharmaceutical product, where the resin is configured to be activated by a medium of the mixture. The device further includes at least one positioning material disposed adjacent to the resin, where the positioning material is configured to provide mechanical support to the resin to at least partially retain the resin in position. In certain embodiments, the device does not require conditioning immediately prior to filtration.
Abstract:
An article includes a substrate assembly for use in a detector system. The substrate assembly includes a substrate; a sample reception structure secured to the substrate; a test window extending through the substrate; and a fluid channel defined by a surface of the substrate and extending from the sample reception structure to the test window.
Abstract:
Systems and methods employing optical disk drives (202) for quantitative analysis of chemical and biochemical parameters are provided. A system (200) includes an optical disk (204) having at least one sensor region (205), a light source (208) for directing light onto the at least one sensor region, an optical detector (210) for detecting interacted light transmitted from the sensor region, the interacted transmitted light being indicative of a concentration of an environmental parameter disposed on the sensor region (205), and an analog-to-digital converter (220) for quantifying a measurable property of the interacted transmitted light. A method for preparing an optical disk (300) with a plurality of sensor spots (306) is provided. A system (1900) includes a robotic arm (1904) for transmitting the disk through a variety of stations that include dipping the disk into a source of a compound, removing excess amounts of the source, optically scanning the disk, and discarding the disk. A system (200) includes control software for directing the light source (208) and optical detector (210) to specified positions of the disk (204) during disk rotation, and for processing the sensor response data to display a map of the sensor material response, and to improve precision of the measured signal.
Abstract:
The present invention provides an apparatus and method for a noninvasive optical determination of the volume of a fluid in a compartment within a closed system comprising a compartment wherein a fluid resides which is permeable to at least one wavelength of light, a light source and light detecting device configured to obtain spectral data for a fluid for at least one wavelength, a processor adapted to determine the volume of the fluid by correlating the spectral data for a fluid at a known path length with the spectral data for the fluid at an unknown path length and wherein the processor is further configured to control the release of the substance from the compartment to its end use.
