Abstract: A gas analyzer is described comprising a sample cell for containing a gas mixture to be analyzed, a source for producing and directing infrared energy through the sample cell, a rotary filter wheel having at least one filter thereon for passing infrared energy limited to a wavelength band within the characteristic absorption band of a predetermined gas and having a dark level region substantially opaque to infrared energy, a drive for supporting and rotating the filter wheel to successively interpose the filter and the dark level region between the source and the sample cell in the path of the infrared energy directed by the source, a detector for detecting infrared energy passing through the sample cell and producing an electrical signal representative thereof, and a signal processor connected to the detector for producing an output indicating the concentration of the predetermined gas in the sample cell by comparing the electrical signals produced by the detector with the filter positioned in the infrared energy path and with the dark level region positioned in the infrared energy path. The dark level region has a substantially fully reflective surface oriented toward the sample cell when positioned in the infrared energy path whereby infrared energy impinging thereon is reflected.

Abstract: The object of this invention is a double multichromatic photometer including a single light-source and a single detector, particularly for the determination of chemical and clinical analyses, in which the photometer light comes from a single light-source which radiates along three distinct optical paths that converge onto a single detector; two of the optical paths are the first and the second measuring channels, which are alternatively excluded whereas the third optical path is for reference purposes. An optical collimation assembly and a measurement cuvette are inserted into each of the two measuring optical paths or channels. Within said three optical paths is inserted a rotating drum, said drum holds a number of interference filters, allowing the third reference optical path to pass freely, and inserts one filter at a time into one or the other of the two measuring optical paths. Moreover, a rotating shutter controlled by a motor is also provided for the reference optical path, said shutter coordinately rotates with the filter-bearing drum. An opto-electronic assembly, including printed circuit boards and optical couplers are provided for the selection of filters and the measuring channel.

Abstract: This relates to systems and methods for measuring a concentration and type of substance in a sample at a sampling interface. The systems can include a light source, optics, one or more modulators, a reference, a detector, and a controller. The systems and methods disclosed can be capable of accounting for drift originating from the light source, one or more optics, and the detector by sharing one or more components between different measurement light paths. Additionally, the systems can be capable of differentiating between different types of drift and eliminating erroneous measurements due to stray light with the placement of one or more modulators between the light source and the sample or reference. Furthermore, the systems can be capable of detecting the substance along various locations and depths within the sample by mapping a detector pixel and a microoptics to the location and depth in the sample.

Abstract: An apparatus includes a flow cell, an imaging assembly, and a processor. The flow cell includes a channel and a plurality of reaction sites. The imaging assembly is operable to receive light emitted from the reaction sites in response to an excitation light. The processor is configured to drive relative movement between at least a portion of the imaging assembly and the flow cell along a continuous range of motion to thereby enable the imaging assembly to capture images along the length of the channel. The processor is also configured to activate the imaging assembly to capture one or more calibration images of one or more calibration regions of the channel, during a first portion of the continuous range of motion. The processor is also configured to activate the imaging assembly to capture images of the reaction sites during a second portion of the continuous range of motion.
